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-2026-80533 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-2026-80533/ (Markdown: https://insights.sbomify.com/CVE-2026-80533/index.md)","id":"CVE-2026-80533","markdown":"https://insights.sbomify.com/CVE-2026-80533/index.md","name":"CVE-2026-80533","record":{"aliases":["BELL-CVE-2026-80533","DEBIAN-CVE-2026-80533","UBUNTU-CVE-2026-80533"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel XFS","requires_auth":"high_privilege","summary":"A null pointer dereference in the Linux kernel XFS AGI repair code can cause a system crash, requiring local administrative access to trigger.","user_interaction":"not_required","vuln_class":"null_dereference"},"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\nxfs: don't walk off the end of a null sc-\u003esa.agi_bp in AGI repair\n\nLOLLM noticed a longstanding bug where xrep_iunlink_walk_ondisk_bucket\ntries to walk ragi-\u003esc-\u003esa.agi_bp to rebuild the unlinked inode lists.\nUnfortunately, it's possible for agi_bp to be null if the buffer\nverifier fails, so we have to use ragi-\u003eagi_bp (which skips verifier\nchecks) instead.","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":"xfs: don't walk off the end of a null sc-\u003esa.agi_bp in AGI repair","id":"CVE-2026-80533","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"xfs: fix ilock leak on error in xfs_dq_get_next_id","id":"CVE-2026-80534"},"packages":[],"prev":{"headline":"xfs: fix another iunlink infinite loop bug in online fsck","id":"CVE-2026-80532"},"products":["Linux"],"published":"2026-08-26","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":"2026-08-26","vendors":["Linux"]},"summary":"A null pointer dereference in the Linux kernel XFS AGI repair code can cause a system crash, requiring local administrative access to trigger.","url":"https://insights.sbomify.com/CVE-2026-80533/"}
