CVE-2026-89862 — scsi: qla2xxx: Fix BSG job leak on validate flash image error path
In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix BSG job leak on validate flash image error path qla28xx_validate_flash_image() returns QLA_SUCCESS (0) unconditionally, telling the FC BSG transport (fc_bsg_host_dispatch()) that the driver owns and will complete the request. But bsg_job_done() is guarded by "if (!rval)", so on the error path (rval == -EINVAL) neither the driver nor the transport completes the job. The request dangles until it times out, leaking block layer resources. Commit c2c68225b145 ("scsi: qla2xxx: Fix bsg_done() causing double free") added the "if (!rval)" guard to a batch of BSG handlers. That is correct for handlers that also return the error code (the transport then completes the job once via fail_host_msg), but this function returns QLA_SUCCESS unconditionally, so the guard turned a correct single completion into a leak. Always call bsg_job_done(): bsg_reply->result is DID_OK and the error is reported in vendor_rsp[0], and since the function returns 0 the transport will not complete the job a second time.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- EPSS 0.2% (30-day exploitation probability)+1
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Linux Linux).
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Search available logs for exploit probes, errors and authentication anomalies.

What should defenders know first?
CVE-2026-89862 is "scsi: qla2xxx: Fix BSG job leak on validate flash image error path", rated Unknown. It affects Linux (Linux); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. EPSS 0.20% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
