In the Linux kernel, the following vulnerability has been resolved:
scsi: mpi3mr: Fix possible crash when setting up bsg fails
If bsg_setup_queue() fails, the bsg_queue is assigned a non-NULL value.
Consequently, in mpi3mr_bsg_exit(), the condition "if(!mrioc->bsg_queue)"
will not be satisfied, preventing execution from entering
bsg_remove_queue(), which could lead to the following crash:
BUG: kernel NULL pointer dereference, address: 000000000000041c
