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-2026-53192 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-2026-53192/ (Markdown: https://insights.sbomify.com/CVE-2026-53192/index.md)","id":"CVE-2026-53192","markdown":"https://insights.sbomify.com/CVE-2026-53192/index.md","name":"CVE-2026-53192","record":{"aliases":["AZL-90660","BELL-CVE-2026-53192","DEBIAN-CVE-2026-53192","GHSA-jmf6-3v74-7x28","ROOT-OS-DEBIAN-11-CVE-2026-53192","ROOT-OS-DEBIAN-12-CVE-2026-53192","ROOT-OS-UBUNTU-2204-CVE-2026-53192","ROOT-OS-UBUNTU-2404-CVE-2026-53192","UBUNTU-CVE-2026-53192"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel ALSA","requires_auth":"low_privilege","summary":"A use-after-free vulnerability in the Linux kernel ALSA timer allows local attackers to achieve code execution or privilege escalation via a race condition.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"},{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nALSA: timer: Fix UAF at snd_timer_user_params()\n\nAt releasing a timer object, e.g. when a userspace timer\n(CONFIG_SND_UTIMER) gets closed and snd_timer_free() is called, it\ntries to detach the timer instances and release the resources.\nHowever, it's still possible that other in-flight tasks are holding\nthe timer instance where the to-be-deleted timer object is associated,\nand this may lead to racy accesses.\n\nFortunately, most of ioctls dealing with the timer instance list\nalready have the protection with register_mutex, and this also avoids\nsuch races.  But, SNDRV_TIMER_IOCTL_PARAMS isn't protected, hence the\nconcurrent ioctl may lead to use-after-free.\n\nThis patch just adds the guard with register_mutex to protect\nsnd_timer_user_params() for covering the code path as a quick\nworkaround.  It's no hot-path but rather a rarely issued ioctl, so the\nperformance penalty doesn't matter.","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":"ALSA: timer: Fix UAF at snd_timer_user_params()","id":"CVE-2026-53192","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"ALSA: timer: Forcibly close timer instances at closing","id":"CVE-2026-53193"},"packages":[],"prev":{"headline":"io_uring/net: inherit IORING_CQE_F_BUF_MORE across bundle recv retries","id":"CVE-2026-53191"},"products":["Linux"],"published":"2026-06-25","related":[{"cvss_score":8.8,"headline":"Linux Kernel Out-of-Bounds Write","id":"CVE-2026-53266","kev_date_added":"2026-09-18","published":"2026-06-25"},{"cvss_score":8.8,"headline":"Linux Kernel Improper Input Validation","id":"CVE-2013-6282","kev_date_added":"2022-09-15","published":"2013-11-19"},{"cvss_score":8.4,"headline":"Linux Kernel Heap-Based Buffer Overflow","id":"CVE-2022-0185","kev_date_added":"2024-08-21","published":"2022-02-11"},{"cvss_score":8.4,"headline":"Linux Kernel Privilege Escalation","id":"CVE-2013-2094","kev_date_added":"2022-09-15","published":"2013-05-14"},{"cvss_score":7.8,"headline":"Linux Kernel Unspecified","id":"CVE-2026-53362","kev_date_added":"2026-08-27","published":"2026-07-04"},{"cvss_score":7.8,"headline":"Linux Kernel Missing Initialization of a Variable","id":"CVE-2026-46300","kev_date_added":"2026-10-28","published":"2026-05-23"},{"cvss_score":7.8,"headline":"Linux Kernel Race Condition","id":"CVE-2025-39964","kev_date_added":"2026-09-18","published":"2025-10-13"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel ALSA timer allows local attackers to achieve code execution or privilege escalation via a race condition.","url":"https://insights.sbomify.com/CVE-2026-53192/"}
