    "summary": "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.",
