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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":8.8},"cwes":[],"references":["https://git.kernel.org/stable/c/415f5a755cec5164b149037bf294e270b78d36c6","https://git.kernel.org/stable/c/9e6372ec2a3990662ae0a67f56ac0aee19848d5b","https://git.kernel.org/stable/c/e4331c6644db85bc6ceb470bd84bcf371b6dbfa6"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-93284","score":0.00127,"percentile":0.02372,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
