It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-54226 in the wild and no public exploit code.\n\nAffected product: Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2023-54226/ (Markdown: https://insights.sbomify.com/CVE-2023-54226/index.md)","id":"CVE-2023-54226","markdown":"https://insights.sbomify.com/CVE-2023-54226/index.md","name":"CVE-2023-54226","record":{"aliases":["BELL-CVE-2023-54226","DEBIAN-CVE-2023-54226","GHSA-hm7q-645m-qhpj","UBUNTU-CVE-2023-54226"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A data race in the Linux kernel's AF_UNIX socket handling can lead to inconsistent state and potential denial of service.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\naf_unix: Fix data races around sk-\u003esk_shutdown.\n\nKCSAN found a data race around sk-\u003esk_shutdown where unix_release_sock()\nand unix_shutdown() update it under unix_state_lock(), OTOH unix_poll()\nand unix_dgram_poll() read it locklessly.\n\nWe need to annotate the writes and reads with WRITE_ONCE() and READ_ONCE().\n\nBUG: KCSAN: data-race in unix_poll / unix_release_sock\n\nwrite to 0xffff88800d0f8aec of 1 bytes by task 264 on cpu 0:\n unix_release_sock+0x75c/0x910 net/unix/af_unix.c:631\n unix_release+0x59/0x80 net/unix/af_unix.c:1042\n __sock_release+0x7d/0x170 net/socket.c:653\n sock_close+0x19/0x30 net/socket.c:1397\n __fput+0x179/0x5e0 fs/file_table.c:321\n ____fput+0x15/0x20 fs/file_table.c:349\n task_work_run+0x116/0x1a0 kernel/task_work.c:179\n resume_user_mode_work include/linux/resume_user_mode.h:49 [inline]\n exit_to_user_mode_loop kernel/entry/common.c:171 [inline]\n exit_to_user_mode_prepare+0x174/0x180 kernel/entry/common.c:204\n __syscall_exit_to_user_mode_work kernel/entry/common.c:286 [inline]\n syscall_exit_to_user_mode+0x1a/0x30 kernel/entry/common.c:297\n do_syscall_64+0x4b/0x90 arch/x86/entry/common.c:86\n entry_SYSCALL_64_after_hwframe+0x72/0xdc\n\nread to 0xffff88800d0f8aec of 1 bytes by task 222 on cpu 1:\n unix_poll+0xa3/0x2a0 net/unix/af_unix.c:3170\n sock_poll+0xcf/0x2b0 net/socket.c:1385\n vfs_poll include/linux/poll.h:88 [inline]\n ep_item_poll.isra.0+0x78/0xc0 fs/eventpoll.c:855\n ep_send_events fs/eventpoll.c:1694 [inline]\n ep_poll fs/eventpoll.c:1823 [inline]\n do_epoll_wait+0x6c4/0xea0 fs/eventpoll.c:2258\n __do_sys_epoll_wait fs/eventpoll.c:2270 [inline]\n __se_sys_epoll_wait fs/eventpoll.c:2265 [inline]\n __x64_sys_epoll_wait+0xcc/0x190 fs/eventpoll.c:2265\n do_syscall_x64 arch/x86/entry/common.c:50 [inline]\n do_syscall_64+0x3b/0x90 arch/x86/entry/common.c:80\n entry_SYSCALL_64_after_hwframe+0x72/0xdc\n\nvalue changed: 0x00 -\u003e 0x03\n\nReported by Kernel Concurrency Sanitizer on:\nCPU: 1 PID: 222 Comm: dbus-broker Not tainted 6.3.0-rc7-02330-gca6270c12e20 #2\nHardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.16.0-0-gd239552ce722-prebuilt.qemu.org 04/01/2014","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"af_unix: Fix data races around sk-\u003esk_shutdown.","id":"CVE-2023-54226","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2023"},"n_packages":0,"n_references":7,"next":{"headline":"blk-mq: fix tags leak when shrink nr_hw_queues","id":"CVE-2023-54227"},"packages":[],"prev":{"headline":"net: ipa: only reset hashed tables when supported","id":"CVE-2023-54225"},"products":["Linux"],"published":"2025-12-30","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A data race in the Linux kernel's AF_UNIX socket handling can lead to inconsistent state and potential denial of service.","url":"https://insights.sbomify.com/CVE-2023-54226/"}
