In the Linux kernel, the following vulnerability has been resolved:
scsi: mpi3mr: Fix possible crash when setting up bsg fails
If bsgsetupqueue() fails, the bsgqueue is assigned a non-NULL value. Consequently, in mpi3mrbsgexit(), the condition "if(!mrioc->bsgqueue)" will not be satisfied, preventing execution from entering bsgremovequeue(), which could lead to the following crash:
