On the\nerror (out:) path the function frees uctx with kfree() but never removes\nit from the list. This leaves a freed node in fcport->unsol_ctx_head: the\nnext list_add_tail() for that fcport writes through the freed node, and a\nsubsequent list_del() can corrupt the list or panic.\n\nUnlink uctx with list_del() before kfree() on the error path, matching the\nother free sites in qla_nvme_release_lsrsp_cmd_kref() and\nqla2xxx_process_purls_pkt(). qla2x00_rel_sp() in the failure path only\nreturns the SRB to its pool and does not invoke sp->put_fn, so the out:\npath is the sole free and uctx is always still linked there.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97528","source_modified_at":"2026-10-21T12:53:03.891Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"875386b98857822b77ac7f95bdf367b70af5b78c","lessThan":"925a9129a514b7c3bc0a8af01e51868adbb9a83e","status":"affected","versionType":"git"},{"version":"875386b98857822b77ac7f95bdf367b70af5b78c","lessThan":"cbbf1484496aac86038e67ac984949af58009d4b","status":"affected","versionType":"git"},{"version":"875386b98857822b77ac7f95bdf367b70af5b78c","lessThan":"a95fc5f1c12bba1dbff72bd2611e7fad0758831b","status":"affected","versionType":"git"},{"version":"875386b98857822b77ac7f95bdf367b70af5b78c","lessThan":"c55d649a6cc246c3ccd5d118faea230c46b60f35","status":"affected","versionType":"git"},{"version":"875386b98857822b77ac7f95bdf367b70af5b78c","lessThan":"e46160a5d4fa59bf4d5f3412b6b5cb79edb967dd","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97528","source_modified_at":"2026-10-21T12:53:03.891Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.6","status":"affected"},{"version":"0","lessThan":"6.6","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-2026-97528","source_modified_at":"2026-10-21T12:53:03.891Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"925a9129a514b7c3bc0a8af01e51868adbb9a83e","basis":"first unaffected version stated in the CVE record"}],"cvss":8.8,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00338,"percentile":0.25988,"score_date":"2026-10-23"},"published_at":"2026-09-25T10:21:30.130Z","modified_at":"2026-10-21T12:53:03.891Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97528","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T12:53:03.891Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97528","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/925a9129a514b7c3bc0a8af01e51868adbb9a83e"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/cbbf1484496aac86038e67ac984949af58009d4b"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/a95fc5f1c12bba1dbff72bd2611e7fad0758831b"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/c55d649a6cc246c3ccd5d118faea230c46b60f35"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/e46160a5d4fa59bf4d5f3412b6b5cb79edb967dd"}],"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":"2026-10-21T12:53:03.891Z","content_hash":"e04e2bf7e956604b5b3676cc598e35490106f24ef99fab5dd5d8bc5354491d58"}}
