Summary
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
