Page faults take the lock\nshared, so a fault racing the resize can resolve a VCN against the\ntransient runlist state of ntfs_non_resident_attr_expand() and fail\nwith a spurious SIGBUS, and can interleave with the size-change\nepilogue (truncate_pagecache(), i_size_write(),\npagecache_isize_extended()).\n\nTake invalidate_lock exclusively around the whole resize after\ninode_dio_wait(), matching the fallocate path and other filesystems\nsuch as xfs, which wraps truncate in its mmaplock (= invalidate_lock).","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99102","source_modified_at":"2026-10-28T10:34:17.224Z","fetched_at":"2026-10-28T15:55:58.673066Z","product":"Linux","vendor":"Linux","versions":[{"version":"9c87959601e80b39a45250e362e6ddfec17cb0fa","lessThan":"f0b0738ba95731eeafd11352c74f8b48951f67dc","status":"affected","versionType":"git"},{"version":"9c87959601e80b39a45250e362e6ddfec17cb0fa","lessThan":"9cc5761b8f28f9cef72061094eb5e37e2cd44d97","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99102","source_modified_at":"2026-10-28T10:34:17.224Z","fetched_at":"2026-10-28T15:55:58.673066Z","product":"Linux","vendor":"Linux","versions":[{"version":"7.1","status":"affected"},{"version":"0","lessThan":"7.1","status":"unaffected","versionType":"semver"},{"version":"7.2.13","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99102","source_modified_at":"2026-10-28T10:34:17.224Z","fetched_at":"2026-10-28T15:55:58.673066Z","package":{"name":"Linux","ecosystem":null},"version":"9cc5761b8f28f9cef72061094eb5e37e2cd44d97","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-28T10:34:17.224Z","modified_at":"2026-10-28T10:34:17.224Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-99102","fetched_at":"2026-10-28T15:55:58.673066Z","source_modified_at":"2026-10-28T10:34:17.224Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/f0b0738ba95731eeafd11352c74f8b48951f67dc"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/9cc5761b8f28f9cef72061094eb5e37e2cd44d97"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-28T10:34:17.224Z","content_hash":"102680fc2f2cdcb9395cc60d2092601f4f8563b90220f5768872d1bcde876890"}}
