However,\ndrm_pagemap_migration_unlock_put_pages() clears the array as part of its\ncleanup, leaving drm_pagemap_migrate_unmap_pages() with no valid page\ninformation if it is called afterward.\n\nCall drm_pagemap_migrate_unmap_pages() before\ndrm_pagemap_migration_unlock_put_pages() so the pages array remains\nvalid during DMA unmapping.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93284","source_modified_at":"2026-10-19T09:08:38.485Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"f86ad0ed620cb3c91ec7d5468e93ac68d727539d","lessThan":"e4331c6644db85bc6ceb470bd84bcf371b6dbfa6","status":"affected","versionType":"git"},{"version":"f86ad0ed620cb3c91ec7d5468e93ac68d727539d","lessThan":"415f5a755cec5164b149037bf294e270b78d36c6","status":"affected","versionType":"git"},{"version":"f86ad0ed620cb3c91ec7d5468e93ac68d727539d","lessThan":"9e6372ec2a3990662ae0a67f56ac0aee19848d5b","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93284","source_modified_at":"2026-10-19T09:08:38.485Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.17","status":"affected"},{"version":"0","lessThan":"6.17","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.9","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-2026-93284","source_modified_at":"2026-10-19T09:08:38.485Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"415f5a755cec5164b149037bf294e270b78d36c6","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93284","source_modified_at":"2026-10-19T09:08:38.485Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"9e6372ec2a3990662ae0a67f56ac0aee19848d5b","basis":"first unaffected version stated in the CVE record"}],"cvss":8.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00127,"percentile":0.02178,"score_date":"2026-10-23"},"published_at":"2026-09-24T16:02:08.527Z","modified_at":"2026-10-19T09:08:38.485Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-93284","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:08:38.485Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-93284","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/e4331c6644db85bc6ceb470bd84bcf371b6dbfa6"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/415f5a755cec5164b149037bf294e270b78d36c6"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/9e6372ec2a3990662ae0a67f56ac0aee19848d5b"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-19T09:08:38.485Z","content_hash":"007452594e0355c8f8659abc7d4f43522631f805ce19a9b80ce54275bfba832b"}}
