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-2026-99169/ (Markdown: https://insights.sbomify.com/CVE-2026-99169/index.md)","id":"CVE-2026-99169","markdown":"https://insights.sbomify.com/CVE-2026-99169/index.md","name":"CVE-2026-99169","record":{"aliases":["AZL-111317","BELL-CVE-2026-99169","DEBIAN-CVE-2026-99169","GHSA-8p9g-5mhx-rvh4","UBUNTU-CVE-2026-99169"],"analysis":null,"analysis_generated_by":null,"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\nfutex: Fix mm reuse handling for FUT_OFF_MMSHARED\n\nA FUT_OFF_MMSHARED futex is a shared futex that refers to an MM.\nIt is possible for a process to wait on a shared futex with a different MM\nbecause a FUT_OFF_INODE waiter can be requeued onto a FUT_OFF_MMSHARED\nfutex by another process.\nThis can cause FUT_OFF_MMSHARED waiters on a freed MM to consume\nwakeups intended for a newly allocated MM at the same address.\n\nFix it by keying FUT_OFF_MMSHARED using a unique 64-bit per-MM ID.\nLeave private futexes as before to avoid influencing the performance of the\nhotpath.\n\n(Multi-threaded processes typically implicitly use FUT_OFF_MMSHARED by\nsetting clear_child_tid such that it points into anonymous memory, which\ncauses mm_release() in a multi-threaded mm to perform FUTEX_WAKE.)","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":"futex: Fix mm reuse handling for FUT_OFF_MMSHARED","id":"CVE-2026-99169","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"namespace: a mount that copy_tree() leaves out can't take over a lock","id":"CVE-2026-99170"},"packages":[],"prev":{"headline":"mshv_vtl: Check per-CPU register page before mmap","id":"CVE-2026-99168"},"products":["Linux"],"published":"2026-10-28","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":"2026-10-28","vendors":["Linux"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-99169/"}
