Vector：CVSS：2.0/
漏洞简述：
In the Linux kernel, the following vulnerability has been resolved:arp: Prevent overflow in arp_req_get().syzkaller reported an overflown write in arp_req_get(). [0]When ioctl(SIOCGARP) is issued, arp_req_get() looks up an neighbourentry and copies neigh->ha to struct arpreq.arp_ha.sa_data.The arp_ha here is struct sockaddr, not struct sockaddr_storage, sothe sa_data buffer is just 14 bytes.In the splat below, 2 bytes are overflown to the next int field,arp_flags. We initialise the field just after the memcpy(), so it snot a problem.However, when dev->addr_len is greater than 22 (e.g. MAX_ADDR_LEN),arp_netmask is overwritten, which could be set as htonl(0xFFFFFFFFUL)in arp_ioctl() before calling arp_req_get().To avoid the overflow, let s limit the max length of memcpy().Note that commit b5f0de6df6dc ( net: dev: Convert sa_data to flexiblearray in struct sockaddr ) just silenced syzkaller.[0]:memcpy: detected field-spanning write (size 16) of single field r->arp_ha.sa_data at net/ipv4/arp.c:1128 (size 14)WARNING: CPU: 0 PID: 144638 at net/ipv4/arp.c:1128 arp_req_get+0x411/0x4a0 net/ipv4/arp.c:1128Modules linked in:CPU: 0 PID: 144638 Comm: syz-executor.4 Not tainted 6.1.74 #31Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.0-debian-1.16.0-5 04/01/2014RIP: 0010:arp_req_get+0x411/0x4a0 net/ipv4/arp.c:1128Code: fd ff ff e8 41 42 de fb b9 0e 00 00 00 4c 89 fe 48 c7 c2 20 6d ab 87 48 c7 c7 80 6d ab 87 c6 05 25 af 72 04 01 e8 5f 8d ad fb <0f> 0b e9 6c fd ff ff e8 13 42 de fb be 03 00 00 00 4c 89 e7 e8 a6RSP: 0018:ffffc900050b7998 EFLAGS: 00010286RAX: 0000000000000000 RBX: ffff88803a815000 RCX: 0000000000000000RDX: 0000000000000000 RSI: ffffffff8641a44a RDI: 0000000000000001RBP: ffffc900050b7a98 R08: 0000000000000001 R09: 0000000000000000R10: 0000000000000000 R11: 203a7970636d656d R12: ffff888039c54000R13: 1ffff92000a16f37 R14: ffff88803a815084 R15: 0000000000000010FS: 00007f172bf306c0(0000) GS:ffff88805aa00000(0000) knlGS:0000000000000000CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033CR2: 00007f172b3569f0 CR3: 0000000057f12005 CR4: 0000000000770ef0DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400PKRU: 55555554Call Trace: arp_ioctl+0x33f/0x4b0 net/ipv4/arp.c:1261 inet_ioctl+0x314/0x3a0 net/ipv4/af_inet.c:981 sock_do_ioctl+0xdf/0x260 net/socket.c:1204 sock_ioctl+0x3ef/0x650 net/socket.c:1321 vfs_ioctl fs/ioctl.c:51 [inline] __do_sys_ioctl fs/ioctl.c:870 [inline] __se_sys_ioctl fs/ioctl.c:856 [inline] __x64_sys_ioctl+0x18e/0x220 fs/ioctl.c:856 do_syscall_x64 arch/x86/entry/common.c:51 [inline] do_syscall_64+0x37/0x90 arch/x86/entry/common.c:81 entry_SYSCALL_64_after_hwframe+0x64/0xceRIP: 0033:0x7f172b262b8dCode: 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 00 f3 0f 1e fa 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 <48> 3d 01 f0 ff ff 73 01 c3 48 c7 c1 b8 ff ff ff f7 d8 64 89 01 48RSP: 002b:00007f172bf300b8 EFLAGS: 00000246 ORIG_RAX: 0000000000000010RAX: ffffffffffffffda RBX: 00007f172b3abf80 RCX: 00007f172b262b8dRDX: 0000000020000000 RSI: 0000000000008954 RDI: 0000000000000003RBP: 00007f172b2d3493 R08: 0000000000000000 R09: 0000000000000000R10: 0000000000000000 R11: 0000000000000246 R12: 0000000000000000R13: 000000000000000b R14: 00007f172b3abf80 R15: 00007f172bf10000

CVE-2024-26733

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

arp: Prevent overflow in arp_req_get().

syzkaller reported an overflown write in arp_req_get(). [0]

When ioctl(SIOCGARP) is issued, arp_req_get() looks up an neighbour
entry and copies neigh->ha to struct arpreq.arp_ha.sa_data.

The arp_ha here is struct sockaddr, not struct sockaddr_storage, so
the sa_data buffer is just 14 bytes.

In the splat below, 2 bytes are overflown to the next int field,
arp_flags. We initialise the field just after the memcpy(), so it's
not a problem.

However, when dev->addr_len is greater than 22 (e.g. MAX_ADDR_LEN),
arp_netmask is overwritten, which could be set as htonl(0xFFFFFFFFUL)
in arp_ioctl() before calling arp_req_get().

To avoid the overflow, let's limit the max length of memcpy().

Note that commit b5f0de6df6dc ("net: dev: Convert sa_data to flexible
array in struct sockaddr") just silenced syzkaller.

[0]:
memcpy: detected field-spanning write (size 16) of single field "r->arp_ha.sa_data" at net/ipv4/arp.c:1128 (size 14)
