In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
scsi: qla2xxx: Fix BSG job leak on validate flash image error path<\/p>\n
qla28xx_validate_flash_image() returns QLA_SUCCESS (0) unconditionally,
\ntelling the FC BSG transport (fc_bsg_host_dispatch()) that the driver
\nowns and will complete the request. 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.<\/p>\n
Commit 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.<\/p>\n
Always 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.<\/p>\n","protected":false},"excerpt":{"rendered":"
