{"id":"AZL-101513","summary":"CVE-2026-89855 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Serialize flash version read in reset handler\n\nThe \"update cache versions without reset\" sysfs reset operation (0x20261)\ncalls get_flash_version(), which reads hardware flash registers, without\nholding ha-\u003eoptrom_mutex. The VPD update path serializes the same call\nunder optrom_mutex, so this reset path can interleave its flash register\naccesses with a concurrent VPD or optrom flash operation and corrupt the\nreads.\n\nHold ha-\u003eoptrom_mutex across the get_flash_version() call to match the\nVPD update path.","modified":"2026-09-18T05:37:08Z","published":"2026-09-16T11:16:53Z","upstream":["CVE-2026-89855"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89855"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-101513.json"}}],"schema_version":"1.9.0"}
