{"id":"CVE-2026-89850","summary":"scsi: qla2xxx: Don't query firmware state while chip is down","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Don't query firmware state while chip is down\n\nqla2x00_fw_state_show() initializes rval to QLA_FUNCTION_FAILED and jumps\nto the out: label when the chip is down or EEH is busy. The out: block\nthen re-issued qla2x00_get_firmware_state() because rval != QLA_SUCCESS,\ndefeating the chip-down/EEH-busy guards and issuing a mailbox command\n(outside optrom_mutex) during ISP reset or PCI error recovery, which can\nhang the adapter. It also turned a normal in-lock mailbox failure into a\nsecond unsynchronized mailbox attempt.\n\nMake the out: fallback only mark the firmware state as unknown. The\nmailbox is now issued at most once, inside optrom_mutex, and only when\nthe chip is up and not EEH-busy.","modified":"2026-09-18T03:48:33.606710869Z","published":"2026-09-16T10:31:24.121Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89850.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/178d984e8875292582e4295cf559b2b11d3c9325"},{"type":"WEB","url":"https://git.kernel.org/stable/c/22f44f77da496bc355479c08a0a9dbc9ad42ba42"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7bc2baed8a3d6a1e2a3f6b78d245f25d1e18a749"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a194684853dceaa1d6b7a9a02bc12f479232ad9b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a6374b508893de15fee78583a95f5099d7812e85"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b6a30baa29695fa0eaba4a3a04435a3c1a5cb63d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cba780c01f72f8585ca81ad7304097f8b12ef339"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e0cebe20dcffbed9c078fe30e2d18cd5046d9eff"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89850.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89850"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"b6faaaf796d7bfb00e32ca5c905d55cc43e89448"},{"fixed":"178d984e8875292582e4295cf559b2b11d3c9325"},{"fixed":"cba780c01f72f8585ca81ad7304097f8b12ef339"},{"fixed":"22f44f77da496bc355479c08a0a9dbc9ad42ba42"},{"fixed":"b6a30baa29695fa0eaba4a3a04435a3c1a5cb63d"},{"fixed":"7bc2baed8a3d6a1e2a3f6b78d245f25d1e18a749"},{"fixed":"a194684853dceaa1d6b7a9a02bc12f479232ad9b"},{"fixed":"a6374b508893de15fee78583a95f5099d7812e85"},{"fixed":"e0cebe20dcffbed9c078fe30e2d18cd5046d9eff"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89850.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.20.0"},{"fixed":"5.10.270"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.221"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.188"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.51"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89850.json"}}],"schema_version":"1.9.0"}
