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-2026-72164/ (Markdown: https://insights.sbomify.com/CVE-2026-72164/index.md)","id":"CVE-2026-72164","markdown":"https://insights.sbomify.com/CVE-2026-72164/index.md","name":"CVE-2026-72164","record":{"aliases":["BELL-CVE-2026-72164","DEBIAN-CVE-2026-72164","GHSA-5r4j-cfqp-hv7w","UBUNTU-CVE-2026-72164"],"analysis":null,"analysis_generated_by":null,"assigner":"Linux","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/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\nocfs2: avoid moving extents to occupied clusters\n\nFor non-auto OCFS2_IOC_MOVE_EXT operations, userspace supplies a physical\nme_goal.  ocfs2_move_extent() initializes new_phys_cpos from that goal and\nexpects ocfs2_probe_alloc_group() to replace it with a free run in the\ntarget block group.\n\nThe probe currently leaves *phys_cpos unchanged if the scan reaches the\nend of the group without finding a free run.
