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-2026-89475 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-2026-89475/ (Markdown: https://insights.sbomify.com/CVE-2026-89475/index.md)","id":"CVE-2026-89475","markdown":"https://insights.sbomify.com/CVE-2026-89475/index.md","name":"CVE-2026-89475","record":{"aliases":["AZL-100208","BELL-CVE-2026-89475","DEBIAN-CVE-2026-89475","GHSA-pg63-6v2p-p54j","UBUNTU-CVE-2026-89475"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"none","summary":"A use-after-free in the bq24257 power supply driver allows local attackers to execute arbitrary code or escalate privileges via race conditions 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: bq24257: fix use-after-free on remove\n\nThe STAT-pin interrupt is devm-managed, so it stays armed until the devm\ncleanup that runs after remove() returns. remove() cancels\nbq-\u003eiilimit_setup_work while the threaded handler can still fire; that\nhandler reschedules the work and dereferences bq, so the work runs\nagainst freed memory once devm frees bq.\n\nMake the delayed work device-managed with devm_delayed_work_autocancel(),\nregistered before the interrupt request.
