The vport is only unlinked from vp_list later,\nin qla24xx_deallocate_vp_id(), which clears vp_map[idx] (RESET_VP_IDX)\nbut does not touch host_map. In the window in between, report ID\nacquisition can still find the vport on vp_list and call\nqla_update_host_map(); with d_id already zeroed it takes the\nbtree_insert32() path and re-inserts the dying vport into host_map.\nNothing cleans that entry afterwards, so once scsi_host_put() frees the\nvha a later host_map lookup dereferences freed memory.\n\nSkip a vport that has VPORT_DELETE set before taking the reference, so it\nis neither re-registered nor scheduled for DPC re-registration. This\nmirrors the existing guard in qla2x00_alert_all_vps().","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97531","source_modified_at":"2026-10-21T12:53:07.214Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"41dc529a4602ac737020f423f84686a81de38e6d","lessThan":"40dcd4a71a52414b47fbba2f956387f1077c6c15","status":"affected","versionType":"git"},{"version":"41dc529a4602ac737020f423f84686a81de38e6d","lessThan":"20bb54601d2655e83795b73499c89f6b1cb31016","status":"affected","versionType":"git"},{"version":"41dc529a4602ac737020f423f84686a81de38e6d","lessThan":"d61e8de98c5a52978fb1edd95fe4dde3131b280e","status":"affected","versionType":"git"},{"version":"41dc529a4602ac737020f423f84686a81de38e6d","lessThan":"7a83979d92782f83c90888ebe19bdc9420521940","status":"affected","versionType":"git"},{"version":"41dc529a4602ac737020f423f84686a81de38e6d","lessThan":"23582731afa35031c94fadb71a4f3b4afd094649","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97531","source_modified_at":"2026-10-21T12:53:07.214Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"4.11","status":"affected"},{"version":"0","lessThan":"4.11","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.112","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.7","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-2026-97531","source_modified_at":"2026-10-21T12:53:07.214Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"40dcd4a71a52414b47fbba2f956387f1077c6c15","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97531","source_modified_at":"2026-10-21T12:53:07.214Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"20bb54601d2655e83795b73499c89f6b1cb31016","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97531","source_modified_at":"2026-10-21T12:53:07.214Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"7a83979d92782f83c90888ebe19bdc9420521940","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97531","source_modified_at":"2026-10-21T12:53:07.214Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"23582731afa35031c94fadb71a4f3b4afd094649","basis":"first unaffected version stated in the CVE record"}],"cvss":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00292,"percentile":0.2069,"score_date":"2026-10-23"},"published_at":"2026-09-25T10:21:31.968Z","modified_at":"2026-10-21T12:53:07.214Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97531","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T12:53:07.214Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97531","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/40dcd4a71a52414b47fbba2f956387f1077c6c15"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/20bb54601d2655e83795b73499c89f6b1cb31016"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/d61e8de98c5a52978fb1edd95fe4dde3131b280e"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/7a83979d92782f83c90888ebe19bdc9420521940"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/23582731afa35031c94fadb71a4f3b4afd094649"}],"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":"2026-10-21T12:53:07.214Z","content_hash":"7f0de8abdf3a1fbafbdfe70e63560ba8af5bfc10f88a0c6bf0bf437d5ceae4e2"}}
