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-2026-89877 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-2026-89877/ (Markdown: https://insights.sbomify.com/CVE-2026-89877/index.md)","id":"CVE-2026-89877","markdown":"https://insights.sbomify.com/CVE-2026-89877/index.md","name":"CVE-2026-89877","record":{"aliases":["AZL-101640","BELL-CVE-2026-89877","DEBIAN-CVE-2026-89877","GHSA-33q9-xpr9-fmxv","UBUNTU-CVE-2026-89877"],"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 saa7164 media driver allows attackers to cause denial of service or execute code via improper cleanup on resource allocation failure.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: saa7164: fix cleanup on resource allocation failure\n\nsaa7164_dev_setup() adds the device to the global saa7164_devlist before\nrequesting the PCI BAR memory regions.\n\nIf get_resources() fails, saa7164_dev_setup() decrements the device count\nand returns an error, but leaves the device on saa7164_devlist.
