Overview

CVE-2026-89862 is a known-severity vulnerability. It was published on September 16, 2026.

Technical description

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],

How can CyberStrike help with CVE-2026-89862?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-89862 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
