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-2026-53354 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-2026-53354/ (Markdown: https://insights.sbomify.com/CVE-2026-53354/index.md)","id":"CVE-2026-53354","markdown":"https://insights.sbomify.com/CVE-2026-53354/index.md","name":"CVE-2026-53354","record":{"aliases":["AZL-91613","BELL-CVE-2026-53354","DEBIAN-CVE-2026-53354","GHSA-j98r-r99h-p736","ROOT-OS-DEBIAN-11-CVE-2026-53354","ROOT-OS-DEBIAN-12-CVE-2026-53354","ROOT-OS-UBUNTU-2204-CVE-2026-53354","ROOT-OS-UBUNTU-2404-CVE-2026-53354","UBUNTU-CVE-2026-53354"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"Attackers can exploit a race condition in Arm CPU TLB invalidation to read or modify stale memory data, requiring kernel patches.","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":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/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\narm64: errata: Mitigate TLBI errata on various Arm CPUs\n\nA number of CPUs developed by Arm suffer from errata whereby a broadcast\nTLBI;DSB sequence may complete before the global observation of writes\nwhich are translated by an affected TLB entry.\n\nThese errata ONLY affect the completion of memory accesses which have\nbeen translated by an invalidated TLB entry, and these errata DO NOT\naffect the actual invalidation of TLB entries. TLB entries are removed\ncorrectly.\n\nThis issue has been assigned CVE ID CVE-2025-10263.\n\nTo mitigate this issue, Arm recommends that software follows any\naffected TLBI;DSB sequence with an additional TLBI;DSB, which will\nensure that all memory write effects affected by the first TLBI have\nbeen globally observed. The additional TLBI can use any operation that\nis broadcast to affected CPUs, and the additional DSB can use any option\nthat is sufficient to complete the additional TLBI.\n\nThe ARM64_WORKAROUND_REPEAT_TLBI workaround is sufficient to mitigate\nthe issue. Enable this workaround for affected CPUs, and update the\nsilicon errata documentation accordingly.\n\nNote that due to the manner in which Arm develops IP and tracks errata,\nsome CPUs share a common erratum number.","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":"arm64: errata: Mitigate TLBI errata on various Arm CPUs","id":"CVE-2026-53354","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"linux:linux_kernel","products":["linux:linux_kernel"],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":9,"next":{"headline":"net: rds: clear i_sends on setup unwind","id":"CVE-2026-53355"},"packages":[],"prev":{"headline":"hsr: Remove WARN_ONCE() in hsr_addr_is_self().","id":"CVE-2026-53353"},"products":["Linux"],"published":"2026-07-01","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":"Attackers can exploit a race condition in Arm CPU TLB invalidation to read or modify stale memory data, requiring kernel patches.","url":"https://insights.sbomify.com/CVE-2026-53354/"}
