Overview

About vulnerability

In the Linux kernel, the following vulnerability has been resolved:

scsi: Revert “scsi: qla2xxx: Perform lockless command completion in abort path”

This reverts commit 0367076b0817d5c75dfb83001ce7ce5c64d803a9.

The commit being reverted added code to __qla2x00_abort_all_cmds() to call sp->done() without holding a spinlock. But unlike the older code below it, this new code failed to check sp->cmd_type and just assumed TYPE_SRB, which results in a jump to an invalid pointer in target-mode with TYPE_TGT_CMD:

Then commit 4475afa2646d (“scsi: qla2xxx: Complete command early within lock”) added the spinlock back, because not having the lock caused a race and a crash. But qla2x00_abort_srb() in the switch below already checks for qla2x00_chip_is_down() and handles it the same way, so the code above the switch is now redundant and still buggy in target-mode. Remove it.
