 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:net/tipc: fix slab-use-after-free Read in tipc_aead_encrypt_doneSyzbot reported a slab-use-after-free with the following call trace:  ==================================================================  BUG: KASAN: slab-use-after-free in tipc_aead_encrypt_done+0x4bd/0x510 net/tipc/crypto.c:840  Read of size 8 at addr ffff88807a733000 by task kworker/1:0/25  Call Trace:   kasan_report+0xd9/0x110 mm/kasan/report.c:601   tipc_aead_encrypt_done+0x4bd/0x510 net/tipc/crypto.c:840   crypto_request_complete include/crypto/algapi.h:266   aead_request_complete include/crypto/internal/aead.h:85   cryptd_aead_crypt+0x3b8/0x750 crypto/cryptd.c:772   crypto_request_complete include/crypto/algapi.h:266   cryptd_queue_worker+0x131/0x200 crypto/cryptd.c:181   process_one_work+0x9fb/0x1b60 kernel/workqueue.c:3231  Allocated by task 8355:   kzalloc_noprof include/linux/slab.h:778   tipc_crypto_start+0xcc/0x9e0 net/tipc/crypto.c:1466   tipc_init_net+0x2dd/0x430 net/tipc/core.c:72   ops_init+0xb9/0x650 net/core/net_namespace.c:139   setup_net+0x435/0xb40 net/core/net_namespace.c:343   copy_net_ns+0x2f0/0x670 net/core/net_namespace.c:508   create_new_namespaces+0x3ea/0xb10 kernel/nsproxy.c:110   unshare_nsproxy_namespaces+0xc0/0x1f0 kernel/nsproxy.c:228   ksys_unshare+0x419/0x970 kernel/fork.c:3323   __do_sys_unshare kernel/fork.c:3394  Freed by task 63:   kfree+0x12a/0x3b0 mm/slub.c:4557   tipc_crypto_stop+0x23c/0x500 net/tipc/crypto.c:1539   tipc_exit_net+0x8c/0x110 net/tipc/core.c:119   ops_exit_list+0xb0/0x180 net/core/net_namespace.c:173   cleanup_net+0x5b7/0xbf0 net/core/net_namespace.c:640   process_one_work+0x9fb/0x1b60 kernel/workqueue.c:3231After freed the tipc_crypto tx by delete namespace, tipc_aead_encrypt_donemay still visit it in cryptd_queue_worker workqueue.I reproduce this issue by:  ip netns add ns1  ip link add veth1 type veth peer name veth2  ip link set veth1 netns ns1  ip netns exec ns1 tipc bearer enable media eth dev veth1  ip netns exec ns1 tipc node set key this_is_a_master_key master  ip netns exec ns1 tipc bearer disable media eth dev veth1  ip netns del ns1The key of reproduction is that, simd_aead_encrypt is interrupted, leadingto crypto_simd_usable() return false. Thus, the cryptd_queue_worker istriggered, and the tipc_crypto tx will be visited.  tipc_disc_timeout    tipc_bearer_xmit_skb      tipc_crypto_xmit        tipc_aead_encrypt          crypto_aead_encrypt            // encrypt()            simd_aead_encrypt              // crypto_simd_usable() is false              child = &ctx->cryptd_tfm->base;  simd_aead_encrypt    crypto_aead_encrypt      // encrypt()      cryptd_aead_encrypt_enqueue        cryptd_aead_enqueue          cryptd_enqueue_request            // trigger cryptd_queue_worker            queue_work_on(smp_processor_id(), cryptd_wq, &cpu_queue->work)Fix this by holding net reference count before encrypt.

  In the Linux kernel, the following vulnerability has been resolved:net/tipc: fix slab-use-after-free Read in tipc_aead_encrypt_doneSyzbot reported a slab-use-after-free with the following call trace:  ==================================================================  BUG: KASAN: slab-use-after-free in tipc_aead_encrypt_done+0x4bd/0x510 net/tipc/crypto.c:840  Read of size 8 at addr ffff88807a733000 by task kworker/1:0/25  Call Trace:   kasan_report+0xd9/0x110 mm/kasan/report.c:601   tipc_aead_encrypt_done+0x4bd/0x510 net/tipc/crypto.c:840   crypto_request_complete include/crypto/algapi.h:266   aead_request_complete include/crypto/internal/aead.h:85   cryptd_aead_crypt+0x3b8/0x750 crypto/cryptd.c:772   crypto_request_complete include/crypto/algapi.h:266   cryptd_queue_worker+0x131/0x200 crypto/cryptd.c:181   process_one_work+0x9fb/0x1b60 kernel/workqueue.c:3231  Allocated by task 8355:   kzalloc_noprof include/linux/slab.h:778   tipc_crypto_start+0xcc/0x9e0 net/tipc/crypto.c:1466   tipc_init_net+0x2dd/0x430 net/tipc/core.c:72   ops_init+0xb9/0x650 net/core/net_namespace.c:139   setup_net+0x435/0xb40 net/core/net_namespace.c:343   copy_net_ns+0x2f0/0x670 net/core/net_namespace.c:508   create_new_namespaces+0x3ea/0xb10 kernel/nsproxy.c:110   unshare_nsproxy_namespaces+0xc0/0x1f0 kernel/nsproxy.c:228   ksys_unshare+0x419/0x970 kernel/fork.c:3323   __do_sys_unshare kernel/fork.c:3394  Freed by task 63:   kfree+0x12a/0x3b0 mm/slub.c:4557   tipc_crypto_stop+0x23c/0x500 net/tipc/crypto.c:1539   tipc_exit_net+0x8c/0x110 net/tipc/core.c:119   ops_exit_list+0xb0/0x180 net/core/net_namespace.c:173   cleanup_net+0x5b7/0xbf0 net/core/net_namespace.c:640   process_one_work+0x9fb/0x1b60 kernel/workqueue.c:3231After freed the tipc_crypto tx by delete namespace, tipc_aead_encrypt_donemay still visit it in cryptd_queue_worker workqueue.I reproduce this issue by:  ip netns add ns1  ip link add veth1 type veth peer name veth2  ip link set veth1 netns ns1  ip netns exec ns1 tipc bearer enable media eth dev veth1  ip netns exec ns1 tipc node set key this_is_a_master_key master  ip netns exec ns1 tipc bearer disable media eth dev veth1  ip netns del ns1The key of reproduction is that, simd_aead_encrypt is interrupted, leadingto crypto_simd_usable() return false. Thus, the cryptd_queue_worker istriggered, and the tipc_crypto tx will be visited.  tipc_disc_timeout    tipc_bearer_xmit_skb      tipc_crypto_xmit        tipc_aead_encrypt          crypto_aead_encrypt            // encrypt()            simd_aead_encrypt              // crypto_simd_usable() is false              child = &#38;ctx-&gt;cryptd_tfm-&gt;base;  simd_aead_encrypt    crypto_aead_encrypt      // encrypt()      cryptd_aead_encrypt_enqueue        cryptd_aead_enqueue          cryptd_enqueue_request            // trigger cryptd_queue_worker            queue_work_on(smp_processor_id(), cryptd_wq, &#38;cpu_queue-&gt;work)Fix this by holding net reference count before encrypt.The Linux kernel CVE team has assigned CVE-2025-38052 to this issue.
