{"id":"CVE-2026-98315","summary":"ntfs: protect runlist updates with the runlist lock","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nntfs: protect runlist updates with the runlist lock\n\nntfs_non_resident_attr_shrink() calls runlist helpers that require the\nrunlist write lock, but did not hold it while freeing clusters and\ntruncating the runlist. Serialize those operations and the resident\nconversion with the runlist lock.\n\nntfs_attr_map_cluster() can merge a newly allocated run before updating\nmapping pairs. If the update fails, free the clusters and restore both\nthe in-memory runlist and on-disk mapping pairs from a saved runlist.\nMark the volume in error if either rollback step fails.","modified":"2026-10-07T02:47:34.253990912Z","published":"2026-10-06T08:46:10.751Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98315.json"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/742797432e8c9b0dd54ecc523c185e26b09d79a0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/91709ba5d6d709b2b663287b7e871e2c6b480502"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98315.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98315"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"495e90fa334828d4119061e2726af51d0a0fb4ed"},{"fixed":"742797432e8c9b0dd54ecc523c185e26b09d79a0"},{"fixed":"91709ba5d6d709b2b663287b7e871e2c6b480502"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98315.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.1.0"},{"fixed":"7.2.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98315.json"}}],"schema_version":"1.9.0"}
