But bsg_job_done() is guarded by \"if\n(!rval)\", so on the error path (rval == -EINVAL) neither the driver nor\nthe transport completes the job. The request dangles until it times out,\nleaking block layer resources.\n\nCommit c2c68225b145 (\"scsi: qla2xxx: Fix bsg_done() causing double\nfree\") added the \"if (!rval)\" guard to a batch of BSG handlers. That is\ncorrect for handlers that also return the error code (the transport then\ncompletes the job once via fail_host_msg), but this function returns\nQLA_SUCCESS unconditionally, so the guard turned a correct single\ncompletion into a leak.\n\nAlways call bsg_job_done(): bsg_reply->result is DID_OK and the error is\nreported in vendor_rsp[0], and since the function returns 0 the\ntransport will not complete the job a second time.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Low · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat OpenShift Container Platform 4 · no fix planned: Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 7, Red Hat Enterprise Linux 8, … · updated 2026-09-23 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-89862.json)","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":30.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":210021,"id":"CVE-2026-89862","ts":1790235654360,"field":"cvss","old":null,"new":"5.5"},{"seq":210020,"id":"CVE-2026-89862","ts":1790235654360,"field":"severity","old":"none","new":"medium"}]}
