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-2026-89463 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-2026-89463/ (Markdown: https://insights.sbomify.com/CVE-2026-89463/index.md)","id":"CVE-2026-89463","markdown":"https://insights.sbomify.com/CVE-2026-89463/index.md","name":"CVE-2026-89463","record":{"aliases":["AZL-100079","BELL-CVE-2026-89463","DEBIAN-CVE-2026-89463","GHSA-p52j-g5j4-c2w7","UBUNTU-CVE-2026-89463"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A use-after-free vulnerability in the Linux kernel UCS1002 power supply driver allows local attackers to cause denial of service or execute code during device removal.","user_interaction":"not_required","vuln_class":"use_after_free"},"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\npower: supply: ucs1002: fix use-after-free on remove\n\nucs1002 has no remove callback, so unbind runs entirely through devm.\nThe alert IRQ handler queues the health_poll delayed work, and the work\nreschedules itself while the chip reports a bad-health condition.  devm\nfrees the alert IRQ, which only synchronizes the handler; it does not\ncancel the delayed work, which can then run after devm frees the driver\ndata and dereference it.\n\nRegister health_poll with devm_delayed_work_autocancel() before the\nalert IRQ is requested.  devm then frees the IRQ before cancelling the\nwork, so the handler can no longer queue it and the work is cancelled\nbefore the driver data is freed.\n\nThis issue was found by an in-house static analysis tool.","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":"power: supply: ucs1002: fix use-after-free on remove","id":"CVE-2026-89463","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2026"},"n_packages":0,"n_references":7,"next":{"headline":"power: supply: twl4030_charger: cancel workers via devm","id":"CVE-2026-89464"},"packages":[],"prev":{"headline":"power: supply: max17040: propagate register read errors","id":"CVE-2026-89462"},"products":["Linux"],"published":"2026-09-11","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":"2026-10-19","vendors":["Linux"]},"summary":"A use-after-free vulnerability in the Linux kernel UCS1002 power supply driver allows local attackers to cause denial of service or execute code during device removal.","url":"https://insights.sbomify.com/CVE-2026-89463/"}
