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-2026-80805 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-2026-80805/ (Markdown: https://insights.sbomify.com/CVE-2026-80805/index.md)","id":"CVE-2026-80805","markdown":"https://insights.sbomify.com/CVE-2026-80805/index.md","name":"CVE-2026-80805","record":{"aliases":["AZL-99516","BELL-CVE-2026-80805","DEBIAN-CVE-2026-80805","GHSA-m3h7-xg69-2hcv","UBUNTU-CVE-2026-80805"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"An out-of-bounds read in the XFS filesystem allows attackers to cause a denial of service or read sensitive memory.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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: validate attr entry pointer before field access\n\nxfs_attr3_leaf_verify_entry() accesses lentry/rentry fields (namelen,\nvaluelen) before checking if the entry pointer itself is within bounds.\nIf nameidx is crafted to point near the end of the buffer, these field\naccesses can read out-of-bounds before the bounds check at\nname_end \u003e buf_end is performed.\n\nAdd explicit bounds checks for entry pointers before accessing their\nfields.
