Details

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
