In the Linux kernel, the following vulnerability has been resolved:
scsi: mpi3mr: Add NULL checks when resetting request and reply queues
The driver encountered a crash during resource cleanup when the reply and request queues were NULL due to freed memory. This issue occurred when the creation of reply or request queues failed, and the driver freed the memory first, but attempted to mem set the content of the freed memory, leading to a system crash.
Add NULL pointer checks for reply and request queues before accessing the reply/request memory during cleanup
AnalysisAI
Local denial-of-service in the Linux kernel's mpi3mr SCSI driver causes a system crash via NULL pointer dereference during resource cleanup. An authenticated local user on a system using MPI3-based storage controllers can trigger a kernel panic by inducing the error path where queue creation fails: the driver frees reply or request queue memory but subsequently attempts to memset the now-freed (NULL) pointer, crashing the system. …
