{"id":"CVE-2026-89842","summary":"scsi: qla2xxx: Skip NVMe LS reject IOCB when FW not started","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":"2026-09-18T03:48:33.212515553Z","published":"2026-09-16T10:31:16.544Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89842.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2935b730211c5c1433aa6101fa3b55df2b63869a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7c1fc75dd3fb6b6414508fbdf7aeed0d757c9120"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ac4b019ac07844d3f67ea5e48b1d982b2170d1a7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e9bfb56e2c1bda49d3c5442d824569d71eec07e2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f7e46ebffc5781aab3f1f5a5d4350addbb5833f4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89842.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89842"},{"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":"875386b98857822b77ac7f95bdf367b70af5b78c"},{"fixed":"2935b730211c5c1433aa6101fa3b55df2b63869a"},{"fixed":"7c1fc75dd3fb6b6414508fbdf7aeed0d757c9120"},{"fixed":"ac4b019ac07844d3f67ea5e48b1d982b2170d1a7"},{"fixed":"e9bfb56e2c1bda49d3c5442d824569d71eec07e2"},{"fixed":"f7e46ebffc5781aab3f1f5a5d4350addbb5833f4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89842.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.6.0"},{"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-2026-89842.json"}}],"schema_version":"1.9.0"}
