In the Linux kernel, the following vulnerability has been resolved:
scsi: fnic: Fix crash in fnic_wq_cmpl_handler when FDMI times out
When both the RHBA and RPA FDMI requests time out, fnic reuses a frame to
send ABTS for each of them. On send completion, this causes an attempt to
free the same frame twice that leads to a crash.
Fix crash by allocating separate frames for RHBA and RPA, and modify ABTS
logic accordingly.
Tested by checking MDS for FDMI information.
Tested by using instrumented driver to:
- Drop PLOGI response
- Drop RHBA response
- Drop RPA response
- Drop RHBA and RPA response
- Drop PLOGI response + ABTS response
- Drop RHBA response + ABTS response
- Drop RPA response + ABTS response
- Drop RHBA and RPA response + ABTS response for both of them
