Description
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], and since the function returns 0 the
transport will not complete the job a second time.
