{"id":"AZL-101331","summary":"CVE-2026-89842 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: qla2xxx: Skip NVMe LS reject IOCB when FW not started\n\nqla_nvme_xmt_ls_rsp() bails out to the out: label when firmware is not\nstarted (!ha-\u003eflags.fw_started), but the out: path unconditionally calls\nqla_nvme_ls_reject_iocb(), which ends in qla2x00_start_iocbs() and an\nunconditional doorbell write to the request queue in-pointer register.\nThis rings the firmware doorbell and queues an IOCB that stopped or\nresetting firmware cannot consume, and touches MMIO during the reset/EEH\nwindow where fw_started is also clear.\n\nOnly emit the LS reject IOCB (and ring the doorbell) when fw_started is\nset; otherwise just clean up and return. The post-allocation failure\ncases (SRB alloc / qla2x00_start_sp() failure) run with firmware started\nand still send the reject. Apply the same guard to the reject emission\nin qla2xxx_process_purls_pkt().","modified":"2026-09-19T05:33:49Z","published":"2026-09-16T11:16:51Z","upstream":["CVE-2026-89842"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89842"}],"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-101331.json"}}],"schema_version":"1.9.0"}
