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-2023-53329 in the wild and no public exploit code.\n\nAffected product: Linux kernel. 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-2023-53329/ (Markdown: https://insights.sbomify.com/CVE-2023-53329/index.md)","id":"CVE-2023-53329","markdown":"https://insights.sbomify.com/CVE-2023-53329/index.md","name":"CVE-2023-53329","record":{"aliases":["BELL-CVE-2023-53329","DEBIAN-CVE-2023-53329","GHSA-8v8f-6c96-795r","UBUNTU-CVE-2023-53329"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["other"],"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 workqueue subsystem can lead to inconsistent statistics, potentially causing undefined behavior or minor instability.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":4.7,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nworkqueue: fix data race with the pwq-\u003estats[] increment\n\nKCSAN has discovered a data race in kernel/workqueue.c:2598:\n\n[ 1863.554079] ==================================================================\n[ 1863.554118] BUG: KCSAN: data-race in process_one_work / process_one_work\n\n[ 1863.554142] write to 0xffff963d99d79998 of 8 bytes by task 5394 on cpu 27:\n[ 1863.554154] process_one_work (kernel/workqueue.c:2598)\n[ 1863.554166] worker_thread (./include/linux/list.h:292 kernel/workqueue.c:2752)\n[ 1863.554177] kthread (kernel/kthread.c:389)\n[ 1863.554186] ret_from_fork (arch/x86/kernel/process.c:145)\n[ 1863.554197] ret_from_fork_asm (arch/x86/entry/entry_64.S:312)\n\n[ 1863.554213] read to 0xffff963d99d79998 of 8 bytes by task 5450 on cpu 12:\n[ 1863.554224] process_one_work (kernel/workqueue.c:2598)\n[ 1863.554235] worker_thread (./include/linux/list.h:292 kernel/workqueue.c:2752)\n[ 1863.554247] kthread (kernel/kthread.c:389)\n[ 1863.554255] ret_from_fork (arch/x86/kernel/process.c:145)\n[ 1863.554266] ret_from_fork_asm (arch/x86/entry/entry_64.S:312)\n\n[ 1863.554280] value changed: 0x0000000000001766 -\u003e 0x000000000000176a\n\n[ 1863.554295] Reported by Kernel Concurrency Sanitizer on:\n[ 1863.554303] CPU: 12 PID: 5450 Comm: kworker/u64:1 Tainted: G             L     6.5.0-rc6+ #44\n[ 1863.554314] Hardware name: ASRock X670E PG Lightning/X670E PG Lightning, BIOS 1.21 04/26/2023\n[ 1863.554322] Workqueue: btrfs-endio btrfs_end_bio_work [btrfs]\n[ 1863.554941] ==================================================================\n\n    lockdep_invariant_state(true);\n→   pwq-\u003estats[PWQ_STAT_STARTED]++;\n    trace_workqueue_execute_start(work);\n    worker-\u003ecurrent_func(work);\n\nMoving pwq-\u003estats[PWQ_STAT_STARTED]++;
