NULL Pointer Dereference in Linux Kernel qedf SCSI Driver

Publication date: 2025-12-30

Last updated on: 2025-12-30

Description
In the Linux kernel, the following vulnerability has been resolved: scsi: qedf: Fix NULL dereference in error handling Smatch reported: drivers/scsi/qedf/qedf_main.c:3056 qedf_alloc_global_queues() warn: missing unwind goto? At this point in the function, nothing has been allocated so we can return directly. In particular the "qedf->global_queues" have not been allocated so calling qedf_free_global_queues() will lead to a NULL dereference when we check if (!gl[i]) and "gl" is NULL.

Can you explain this vulnerability to me?

This vulnerability is a NULL pointer dereference in the Linux kernel's qedf driver for SCSI devices. It occurs in the error handling code of the function qedf_alloc_global_queues(), where the code attempts to free global queues that have not been allocated yet, leading to a NULL dereference and potential kernel crash.


How can this vulnerability impact me? :

This vulnerability can cause a kernel crash or system instability due to a NULL pointer dereference in the qedf driver. This may lead to denial of service or unexpected system behavior on affected systems using the qedf driver.
