{"schema":"threatline.record/2","record":{"id":"CVE-2026-97527","aliases":[],"summary":"scsi: qla2xxx: Serialize NVMe unsol ctx list with a per-fcport lock","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Serialize NVMe unsol ctx list with a per-fcport lock\n\nThe fcport->unsol_ctx_head list is modified from several contexts without\na common lock. Entries are added in qla2xxx_process_purls_iocb() from the\nresponse queue ISR (under the qpair qp_lock), while they are removed from\nqla2xxx_process_purls_pkt() (DPC/purex worker), qla_nvme_xmt_ls_rsp()\n(NVMe-FC transport callback) and qla_nvme_release_lsrsp_cmd_kref() (SRB\ncompletion). The qpair qp_lock cannot serialize this per-fcport list since\nmultiqueue adapters add entries through different qpairs, so a concurrent\nadd and delete (or two concurrent deletes) can corrupt the list pointers.\n\nIntroduce a dedicated per-fcport spinlock, unsol_ctx_lock, initialized in\nqla2x00_alloc_fcport(), and take it around every list_add_tail()/list_del()\non unsol_ctx_head. The add nests under the existing qp_lock; no delete path\ntakes qp_lock, so the lock order is consistent and deadlock free.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97527","source_modified_at":"2026-10-21T12:53:02.776Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"875386b98857822b77ac7f95bdf367b70af5b78c","lessThan":"6c71726cdfda93ae169a75c7b1697eb870303125","status":"affected","versionType":"git"},{"version":"875386b98857822b77ac7f95bdf367b70af5b78c","lessThan":"c1ee12eecbab9674fb73c9e00a93fac655d5a5dc","status":"affected","versionType":"git"},{"version":"875386b98857822b77ac7f95bdf367b70af5b78c","lessThan":"b211d138cad86f749826d6132db6388eded992d8","status":"affected","versionType":"git"},{"version":"875386b98857822b77ac7f95bdf367b70af5b78c","lessThan":"4d8ad6bc8cc5eff1870cef00a0d611f38f8b6bd0","status":"affected","versionType":"git"},{"version":"875386b98857822b77ac7f95bdf367b70af5b78c","lessThan":"76da0c43c63eb0496649e372ac64466364d0fe7d","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97527","source_modified_at":"2026-10-21T12:53:02.776Z","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-2026-97527","source_modified_at":"2026-10-21T12:53:02.776Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"6c71726cdfda93ae169a75c7b1697eb870303125","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97527","source_modified_at":"2026-10-21T12:53:02.776Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"4d8ad6bc8cc5eff1870cef00a0d611f38f8b6bd0","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97527","source_modified_at":"2026-10-21T12:53:02.776Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"76da0c43c63eb0496649e372ac64466364d0fe7d","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":"2026-09-25T10:21:29.521Z","modified_at":"2026-10-21T12:53:02.776Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97527","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T12:53:02.776Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97527","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/6c71726cdfda93ae169a75c7b1697eb870303125"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/c1ee12eecbab9674fb73c9e00a93fac655d5a5dc"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/b211d138cad86f749826d6132db6388eded992d8"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/4d8ad6bc8cc5eff1870cef00a0d611f38f8b6bd0"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/76da0c43c63eb0496649e372ac64466364d0fe7d"}],"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":"2026-10-21T12:53:02.776Z","content_hash":"d08ba32a756feaa882d3039fee2029edf6a0d47eacba0b7d42374c23d1f496a7"}}
