漏洞简述：

In the Linux kernel, the following vulnerability has been resolved:bpf: fix OOB devmap writes when deleting elementsJordy reported issue against XSKMAP which also applies to DEVMAP - theindex used for accessing map entry, due to being a signed integer,causes the OOB writes. Fix is simple as changing the type from int tou32, however, when compared to XSKMAP case, one more thing needs to beaddressed.When map is released from system via dev_map_free(), we iterate throughall of the entries and an iterator variable is also an int, whichimplies OOB accesses. Again, change it to be u32.Example splat below:[ 160.724676] BUG: unable to handle page fault for address: ffffc8fc2c001000[ 160.731662] #PF: supervisor read access in kernel mode[ 160.736876] #PF: error_code(0x0000) - not-present page[ 160.742095] PGD 0 P4D 0[ 160.744678] Oops: Oops: 0000 [#1] PREEMPT SMP[ 160.749106] CPU: 1 UID: 0 PID: 520 Comm: kworker/u145:12 Not tainted 6.12.0-rc1+ #487[ 160.757050] Hardware name: Intel Corporation S2600WFT/S2600WFT, BIOS SE5C620.86B.02.01.0008.031920191559 03/19/2019[ 160.767642] Workqueue: events_unbound bpf_map_free_deferred[ 160.773308] RIP: 0010:dev_map_free+0x77/0x170[ 160.777735] Code: 00 e8 fd 91 ed ff e8 b8 73 ed ff 41 83 7d 18 19 74 6e 41 8b 45 24 49 8b bd f8 00 00 00 31 db 85 c0 74 48 48 63 c3 48 8d 04 c7 <48> 8b 28 48 85 ed 74 30 48 8b 7d 18 48 85 ff 74 05 e8 b3 52 fa ff[ 160.796777] RSP: 0018:ffffc9000ee1fe38 EFLAGS: 00010202[ 160.802086] RAX: ffffc8fc2c001000 RBX: 0000000080000000 RCX: 0000000000000024[ 160.809331] RDX: 0000000000000000 RSI: 0000000000000024 RDI: ffffc9002c001000[ 160.816576] RBP: 0000000000000000 R08: 0000000000000023 R09: 0000000000000001[ 160.823823] R10: 0000000000000001 R11: 00000000000ee6b2 R12: dead000000000122[ 160.831066] R13: ffff88810c928e00 R14: ffff8881002df405 R15: 0000000000000000[ 160.838310] FS: 0000000000000000(0000) GS:ffff8897e0c40000(0000) knlGS:0000000000000000[ 160.846528] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 160.852357] CR2: ffffc8fc2c001000 CR3: 0000000005c32006 CR4: 00000000007726f0[ 160.859604] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[ 160.866847] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400[ 160.874092] PKRU: 55555554[ 160.876847] Call Trace:[ 160.879338] <TASK>[ 160.881477] ? __die+0x20/0x60[ 160.884586] ? page_fault_oops+0x15a/0x450[ 160.888746] ? search_extable+0x22/0x30[ 160.892647] ? search_bpf_extables+0x5f/0x80[ 160.896988] ? exc_page_fault+0xa9/0x140[ 160.900973] ? asm_exc_page_fault+0x22/0x30[ 160.905232] ? dev_map_free+0x77/0x170[ 160.909043] ? dev_map_free+0x58/0x170[ 160.912857] bpf_map_free_deferred+0x51/0x90[ 160.917196] process_one_work+0x142/0x370[ 160.921272] worker_thread+0x29e/0x3b0[ 160.925082] ? rescuer_thread+0x4b0/0x4b0[ 160.929157] kthread+0xd4/0x110[ 160.932355] ? kthread_park+0x80/0x80[ 160.936079] ret_from_fork+0x2d/0x50[ 160.943396] ? kthread_park+0x80/0x80[ 160.950803] ret_from_fork_asm+0x11/0x20[ 160.958482] </TASK>

二、漏洞分析结构反馈

影响性分析说明：

In the Linux kernel, the following vulnerability has been resolved:bpf: fix OOB devmap writes when deleting elementsJordy reported issue against XSKMAP which also applies to DEVMAP - theindex used for accessing map entry, due to being a signed integer,causes the OOB writes. Fix is simple as changing the type from int tou32, however, when compared to XSKMAP case, one more thing needs to beaddressed.When map is released from system via dev_map_free(), we iterate throughall of the entries and an iterator variable is also an int, whichimplies OOB accesses. Again, change it to be u32.Example splat below:[ 160.724676] BUG: unable to handle page fault for address: ffffc8fc2c001000[ 160.731662] #PF: supervisor read access in kernel mode[ 160.736876] #PF: error_code(0x0000) - not-present page[ 160.742095] PGD 0 P4D 0[ 160.744678] Oops: Oops: 0000 [#1] PREEMPT SMP[ 160.749106] CPU: 1 UID: 0 PID: 520 Comm: kworker/u145:12 Not tainted 6.12.0-rc1+ #487[ 160.757050] Hardware name: Intel Corporation S2600WFT/S2600WFT, BIOS SE5C620.86B.02.01.0008.031920191559 03/19/2019[ 160.767642] Workqueue: events_unbound bpf_map_free_deferred[ 160.773308] RIP: 0010:dev_map_free+0x77/0x170[ 160.777735] Code: 00 e8 fd 91 ed ff e8 b8 73 ed ff 41 83 7d 18 19 74 6e 41 8b 45 24 49 8b bd f8 00 00 00 31 db 85 c0 74 48 48 63 c3 48 8d 04 c7 &lt;48&gt; 8b 28 48 85 ed 74 30 48 8b 7d 18 48 85 ff 74 05 e8 b3 52 fa ff[ 160.796777] RSP: 0018:ffffc9000ee1fe38 EFLAGS: 00010202[ 160.802086] RAX: ffffc8fc2c001000 RBX: 0000000080000000 RCX: 0000000000000024[ 160.809331] RDX: 0000000000000000 RSI: 0000000000000024 RDI: ffffc9002c001000[ 160.816576] RBP: 0000000000000000 R08: 0000000000000023 R09: 0000000000000001[ 160.823823] R10: 0000000000000001 R11: 00000000000ee6b2 R12: dead000000000122[ 160.831066] R13: ffff88810c928e00 R14: ffff8881002df405 R15: 0000000000000000[ 160.838310] FS: 0000000000000000(0000) GS:ffff8897e0c40000(0000) knlGS:0000000000000000[ 160.846528] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 160.852357] CR2: ffffc8fc2c001000 CR3: 0000000005c32006 CR4: 00000000007726f0[ 160.859604] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[ 160.866847] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400[ 160.874092] PKRU: 55555554[ 160.876847] Call Trace:[ 160.879338] &lt;TASK&gt;[ 160.881477] ? __die+0x20/0x60[ 160.884586] ? page_fault_oops+0x15a/0x450[ 160.888746] ? search_extable+0x22/0x30[ 160.892647] ? search_bpf_extables+0x5f/0x80[ 160.896988] ? exc_page_fault+0xa9/0x140[ 160.900973] ? asm_exc_page_fault+0x22/0x30[ 160.905232] ? dev_map_free+0x77/0x170[ 160.909043] ? dev_map_free+0x58/0x170[ 160.912857] bpf_map_free_deferred+0x51/0x90[ 160.917196] process_one_work+0x142/0x370[ 160.921272] worker_thread+0x29e/0x3b0[ 160.925082] ? rescuer_thread+0x4b0/0x4b0[ 160.929157] kthread+0xd4/0x110[ 160.932355] ? kthread_park+0x80/0x80[ 160.936079] ret_from_fork+0x2d/0x50[ 160.943396] ? kthread_park+0x80/0x80[ 160.950803] ret_from_fork_asm+0x11/0x20[ 160.958482] &lt;/TASK&gt;The Linux kernel CVE team has assigned CVE-2024-56615 to this issue.

漏洞简述：

In the Linux kernel, the following vulnerability has been resolved:bpf: fix OOB devmap writes when deleting elementsJordy reported issue against XSKMAP which also applies to DEVMAP - theindex used for accessing map entry, due to being a signed integer,causes the OOB writes. Fix is simple as changing the type from int tou32, however, when compared to XSKMAP case, one more thing needs to beaddressed.When map is released from system via dev_map_free(), we iterate throughall of the entries and an iterator variable is also an int, whichimplies OOB accesses.

漏洞简述：

In the Linux kernel, the following vulnerability has been resolved:bpf: fix OOB devmap writes when deleting elementsJordy reported issue against XSKMAP which also applies to DEVMAP - theindex used for accessing map entry, due to being a signed integer,causes the OOB writes. Fix is simple as changing the type from int tou32, however, when compared to XSKMAP case, one more thing needs to beaddressed.When map is released from system via dev_map_free(), we iterate throughall of the entries and an iterator variable is also an int, whichimplies OOB accesses. Again, change it to be u32.Example splat below:[ 160.724676] BUG: unable to handle page fault for address: ffffc8fc2c001000[ 160.731662] #PF: supervisor read access in kernel mode[ 160.736876] #PF: error_code(0x0000) - not-present page[ 160.742095] PGD 0 P4D 0[ 160.744678] Oops: Oops: 0000 [#1] PREEMPT SMP[ 160.749106] CPU: 1 UID: 0 PID: 520 Comm: kworker/u145:12 Not tainted 6.12.0-rc1+ #487[ 160.757050] Hardware name: Intel Corporation S2600WFT/S2600WFT, BIOS SE5C620.86B.02.01.0008.031920191559 03/19/2019[ 160.767642] Workqueue: events_unbound bpf_map_free_deferred[ 160.773308] RIP: 0010:dev_map_free+0x77/0x170[ 160.777735] Code: 00 e8 fd 91 ed ff e8 b8 73 ed ff 41 83 7d 18 19 74 6e 41 8b 45 24 49 8b bd f8 00 00 00 31 db 85 c0 74 48 48 63 c3 48 8d 04 c7 <48> 8b 28 48 85 ed 74 30 48 8b 7d 18 48 85 ff 74 05 e8 b3 52 fa ff[ 160.796777] RSP: 0018:ffffc9000ee1fe38 EFLAGS: 00010202[ 160.802086] RAX: ffffc8fc2c001000 RBX: 0000000080000000 RCX: 0000000000000024[ 160.809331] RDX: 0000000000000000 RSI: 0000000000000024 RDI: ffffc9002c001000[ 160.816576] RBP: 0000000000000000 R08: 0000000000000023 R09: 0000000000000001[ 160.823823] R10: 0000000000000001 R11: 00000000000ee6b2 R12: dead000000000122[ 160.831066] R13: ffff88810c928e00 R14: ffff8881002df405 R15: 0000000000000000[ 160.838310] FS: 0000000000000000(0000) GS:ffff8897e0c40000(0000) knlGS:0000000000000000[ 160.846528] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 160.852357] CR2: ffffc8fc2c001000 CR3: 0000000005c32006 CR4: 00000000007726f0[ 160.859604] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[ 160.866847] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400[ 160.874092] PKRU: 55555554[ 160.876847] Call Trace:[ 160.879338] <TASK>[ 160.881477] ? __die+0x20/0x60[ 160.884586] ? page_fault_oops+0x15a/0x450[ 160.888746] ? search_extable+0x22/0x30[ 160.892647] ? search_bpf_extables+0x5f/0x80[ 160.896988] ? exc_page_fault+0xa9/0x140[ 160.900973] ? asm_exc_page_fault+0x22/0x30[ 160.905232] ? dev_map_free+0x77/0x170[ 160.909043] ? dev_map_free+0x58/0x170[ 160.912857] bpf_map_free_deferred+0x51/0x90[ 160.917196] process_one_work+0x142/0x370[ 160.921272] worker_thread+0x29e/0x3b0[ 160.925082] ? rescuer_thread+0x4b0/0x4b0[ 160.929157] kthread+0xd4/0x110[ 160.932355] ? kthread_park+0x80/0x80[ 160.936079] ret_from_fork+0x2d/0x50[ 160.943396] ? kthread_park+0x80/0x80[ 160.950803] ret_from_fork_asm+0x11/0x20[ 160.958482] </TASK>

二、漏洞分析结构反馈

影响性分析说明：

In the Linux kernel, the following vulnerability has been resolved:bpf: fix OOB devmap writes when deleting elementsJordy reported issue against XSKMAP which also applies to DEVMAP - theindex used for accessing map entry, due to being a signed integer,causes the OOB writes. Fix is simple as changing the type from int tou32, however, when compared to XSKMAP case, one more thing needs to beaddressed.When map is released from system via dev_map_free(), we iterate throughall of the entries and an iterator variable is also an int, whichimplies OOB accesses. Again, change it to be u32.Example splat below:[ 160.724676] BUG: unable to handle page fault for address: ffffc8fc2c001000[ 160.731662] #PF: supervisor read access in kernel mode[ 160.736876] #PF: error_code(0x0000) - not-present page[ 160.742095] PGD 0 P4D 0[ 160.744678] Oops: Oops: 0000 [#1] PREEMPT SMP[ 160.749106] CPU: 1 UID: 0 PID: 520 Comm: kworker/u145:12 Not tainted 6.12.0-rc1+ #487[ 160.757050] Hardware name: Intel Corporation S2600WFT/S2600WFT, BIOS SE5C620.86B.02.01.0008.031920191559 03/19/2019[ 160.767642] Workqueue: events_unbound bpf_map_free_deferred[ 160.773308] RIP: 0010:dev_map_free+0x77/0x170[ 160.777735] Code: 00 e8 fd 91 ed ff e8 b8 73 ed ff 41 83 7d 18 19 74 6e 41 8b 45 24 49 8b bd f8 00 00 00 31 db 85 c0 74 48 48 63 c3 48 8d 04 c7 &lt;48&gt; 8b 28 48 85 ed 74 30 48 8b 7d 18 48 85 ff 74 05 e8 b3 52 fa ff[ 160.796777] RSP: 0018:ffffc9000ee1fe38 EFLAGS: 00010202[ 160.802086] RAX: ffffc8fc2c001000 RBX: 0000000080000000 RCX: 0000000000000024[ 160.809331] RDX: 0000000000000000 RSI: 0000000000000024 RDI: ffffc9002c001000[ 160.816576] RBP: 0000000000000000 R08: 0000000000000023 R09: 0000000000000001[ 160.823823] R10: 0000000000000001 R11: 00000000000ee6b2 R12: dead000000000122[ 160.831066] R13: ffff88810c928e00 R14: ffff8881002df405 R15: 0000000000000000[ 160.838310] FS: 0000000000000000(0000) GS:ffff8897e0c40000(0000) knlGS:0000000000000000[ 160.846528] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 160.852357] CR2: ffffc8fc2c001000 CR3: 0000000005c32006 CR4: 00000000007726f0[ 160.859604] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[ 160.866847] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400[ 160.874092] PKRU: 55555554[ 160.876847] Call Trace:[ 160.879338] &lt;TASK&gt;[ 160.881477] ? __die+0x20/0x60[ 160.884586] ? page_fault_oops+0x15a/0x450[ 160.888746] ? search_extable+0x22/0x30[ 160.892647] ? search_bpf_extables+0x5f/0x80[ 160.896988] ? exc_page_fault+0xa9/0x140[ 160.900973] ? asm_exc_page_fault+0x22/0x30[ 160.905232] ? dev_map_free+0x77/0x170[ 160.909043] ? dev_map_free+0x58/0x170[ 160.912857] bpf_map_free_deferred+0x51/0x90[ 160.917196] process_one_work+0x142/0x370[ 160.921272] worker_thread+0x29e/0x3b0[ 160.925082] ? rescuer_thread+0x4b0/0x4b0[ 160.929157] kthread+0xd4/0x110[ 160.932355] ? kthread_park+0x80/0x80[ 160.936079] ret_from_fork+0x2d/0x50[ 160.943396] ? kthread_park+0x80/0x80[ 160.950803] ret_from_fork_asm+0x11/0x20[ 160.958482] &lt;/TASK&gt;The Linux kernel CVE team has assigned CVE-2024-56615 to this issue.

二、漏洞分析结构反馈

影响性分析说明：

In the Linux kernel, the following vulnerability has been resolved:bpf: fix OOB devmap writes when deleting elementsJordy reported issue against XSKMAP which also applies to DEVMAP - theindex used for accessing map entry, due to being a signed integer,causes the OOB writes. Fix is simple as changing the type from int tou32, however, when compared to XSKMAP case, one more thing needs to beaddressed.When map is released from system via dev_map_free(), we iterate throughall of the entries and an iterator variable is also an int, whichimplies OOB accesses. Again, change it to be u32.Example splat below:[ 160.724676] BUG: unable to handle page fault for address: ffffc8fc2c001000[ 160.731662] #PF: supervisor read access in kernel mode[ 160.736876] #PF: error_code(0x0000) - not-present page[ 160.742095] PGD 0 P4D 0[ 160.744678] Oops: Oops: 0000 [#1] PREEMPT SMP[ 160.749106] CPU: 1 UID: 0 PID: 520 Comm: kworker/u145:12 Not tainted 6.12.0-rc1+ #487[ 160.757050] Hardware name: Intel Corporation S2600WFT/S2600WFT, BIOS SE5C620.86B.02.01.0008.031920191559 03/19/2019[ 160.767642] Workqueue: events_unbound bpf_map_free_deferred[ 160.773308] RIP: 0010:dev_map_free+0x77/0x170[ 160.777735] Code: 00 e8 fd 91 ed ff e8 b8 73 ed ff 41 83 7d 18 19 74 6e 41 8b 45 24 49 8b bd f8 00 00 00 31 db 85 c0 74 48 48 63 c3 48 8d 04 c7 &lt;48&gt; 8b 28 48 85 ed 74 30 48 8b 7d 18 48 85 ff 74 05 e8 b3 52 fa ff[ 160.796777] RSP: 0018:ffffc9000ee1fe38 EFLAGS: 00010202[ 160.802086] RAX: ffffc8fc2c001000 RBX: 0000000080000000 RCX: 0000000000000024[ 160.809331] RDX: 0000000000000000 RSI: 0000000000000024 RDI: ffffc9002c001000[ 160.816576] RBP: 0000000000000000 R08: 0000000000000023 R09: 0000000000000001[ 160.823823] R10: 0000000000000001 R11: 00000000000ee6b2 R12: dead000000000122[ 160.831066] R13: ffff88810c928e00 R14: ffff8881002df405 R15: 0000000000000000[ 160.838310] FS: 0000000000000000(0000) GS:ffff8897e0c40000(0000) knlGS:0000000000000000[ 160.846528] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033[ 160.852357] CR2: ffffc8fc2c001000 CR3: 0000000005c32006 CR4: 00000000007726f0[ 160.859604] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000[ 160.866847] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400[ 160.874092] PKRU: 55555554[ 160.876847] Call Trace:[ 160.879338] &lt;TASK&gt;[ 160.881477] ? __die+0x20/0x60[ 160.884586] ? page_fault_oops+0x15a/0x450[ 160.888746] ? search_extable+0x22/0x30[ 160.892647] ? search_bpf_extables+0x5f/0x80[ 160.896988] ? exc_page_fault+0xa9/0x140[ 160.900973] ? asm_exc_page_fault+0x22/0x30[ 160.905232] ? dev_map_free+0x77/0x170[ 160.909043] ? dev_map_free+0x58/0x170[ 160.912857] bpf_map_free_deferred+0x51/0x90[ 160.917196] process_one_work+0x142/0x370[ 160.921272] worker_thread+0x29e/0x3b0[ 160.925082] ? rescuer_thread+0x4b0/0x4b0[ 160.929157] kthread+0xd4/0x110[ 160.932355] ? kthread_park+0x80/0x80[ 160.936079] ret_from_fork+0x2d/0x50[ 160.943396] ? kthread_park+0x80/0x80[ 160.950803] ret_from_fork_asm+0x11/0x20[ 160.958482] &lt;/TASK&gt;The Linux kernel CVE team has assigned CVE-2024-56615 to this issue.
