If the purgeable\nstate of a pinned bo changes, for example by userspace madvising\nDONTNEED on a VMA of a bo that is also pinned as a scanout buffer,\nthis underflows one count and, after unpin, leaves the other one\npermanently inflated.\n\nOnly update the purgeable flag for pinned bos, and leave the page\naccounting to unpin.\n\n(cherry picked from commit afe6bc012034123fd838328668e609bf57e46bd3)","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99145","source_modified_at":"2026-10-28T10:35:02.038Z","fetched_at":"2026-10-28T15:55:58.673066Z","product":"Linux","vendor":"Linux","versions":[{"version":"536a2ead3a8f2048643da3e8340a4d73fdf71903","lessThan":"135e998dd1e66b8854db7bd356b6563baf8b9d51","status":"affected","versionType":"git"},{"version":"536a2ead3a8f2048643da3e8340a4d73fdf71903","lessThan":"ffbfd3f98f4393e91dffce3a46ccb7cf5329cf2f","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99145","source_modified_at":"2026-10-28T10:35:02.038Z","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-2026-99145","source_modified_at":"2026-10-28T10:35:02.038Z","fetched_at":"2026-10-28T15:55:58.673066Z","package":{"name":"Linux","ecosystem":null},"version":"135e998dd1e66b8854db7bd356b6563baf8b9d51","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":"2026-10-28T10:35:02.038Z","modified_at":"2026-10-28T10:35:02.038Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-99145","fetched_at":"2026-10-28T15:55:58.673066Z","source_modified_at":"2026-10-28T10:35:02.038Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/135e998dd1e66b8854db7bd356b6563baf8b9d51"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/ffbfd3f98f4393e91dffce3a46ccb7cf5329cf2f"}],"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":"2026-10-28T10:35:02.038Z","content_hash":"dc81fe78071df901d6f8bf4063ad3037a33dea77f19d553ca15c03885c677bba"}}
