This races with\nntfs_attr_fallocate(), which merges clusters into the in-memory\nrunlist, drops the runlist lock, and only afterwards zeroes the newly\nallocated clusters on disk; and with the punch-hole/insert/collapse\npaths that free clusters after truncating the cache.\n\nPer Documentation/filesystems/locking.rst, ->page_mkwrite() must ensure\nthere are no truncate/invalidate races, \"usually mapping->invalidate_lock\nis suitable for proper serialization\".  xfs takes its mmaplock (= the\ninvalidate_lock rwsem) shared in exactly this path.\n\nTake invalidate_lock shared around iomap_page_mkwrite().  The read-only\nfault path is already covered because filemap_fault() itself grabs\ninvalidate_lock shared on instantiation/read paths; only page_mkwrite\nwas bypassing it in this driver.","score":null,"severity":"unknown","published":"2026-11-02T16:06:44.163Z","modified":"2026-11-02T16:06:44.163Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"9c87959601e80b39a45250e362e6ddfec17cb0fa","status":"affected","lessThan":"57c0d5281666d150c73e56e6795a4eef3ede8693","versionType":"git"},{"version":"9c87959601e80b39a45250e362e6ddfec17cb0fa","status":"affected","lessThan":"0fecc393f2060e6bc25138df32cb923ec7071c6b","versionType":"git"}],"defaultStatus":"unaffected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-99241"},{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"7.1","status":"affected"},{"version":"0","status":"unaffected","lessThan":"7.1","versionType":"semver"},{"version":"7.2.14","status":"unaffected","lessThanOrEqual":"7.2.*","versionType":"semver"},{"version":"7.3","status":"unaffected","lessThanOrEqual":"*","versionType":"original_commit_for_fix"}],"defaultStatus":"affected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-99241"}],"remediation":[],"references":["https://git.kernel.org/stable/c/57c0d5281666d150c73e56e6795a4eef3ede8693","https://git.kernel.org/stable/c/0fecc393f2060e6bc25138df32cb923ec7071c6b"],"sources":[{"name":"CVE","id":"CVE-2026-99241","modified":"2026-11-02T16:06:44.163Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-99241"}],"assessments":[],"sourceAffected":[],"observedAt":"2026-11-02T16:16:14.351Z","kev":{"status":"not-listed","checkedAt":"2026-11-06T21:20:33.816Z"},"coverage":[{"source":"NVD","status":"available","checkedAt":"2026-11-02T16:20:37.573Z","attemptedAt":"2026-11-02T16:20:37.573Z"},{"source":"GHSA","status":"no-result","checkedAt":"2026-11-02T16:20:37.429Z","attemptedAt":"2026-11-02T16:20:37.429Z"},{"source":"EUVD","status":"no-result","checkedAt":"2026-11-02T16:20:37.878Z","attemptedAt":"2026-11-02T16:20:37.878Z"},{"source":"EPSS","status":"no-result","checkedAt":"2026-11-02T16:20:37.425Z","attemptedAt":"2026-11-02T16:20:37.425Z"}],"evidence":[{"source":"NVD","id":"CVE-2026-99241","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-99241","modified":"2026-11-02T16:17:49.907","checkedAt":"2026-11-02T16:20:37.573Z"}],"aiSummary":null}
