Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.4.0-rc6+

Description The Linux kernel contains a flaw within the vduse module. Specifically, the vduse vdpa set vq affinity callback function may be invoked with a NULL value as the cpu mask when a vduse device is being deleted. This can lead to a NULL pointer dereference, potentially causing a system crash. The issue occurs during the processing of virtual queue (virtqueue) affinity settings.

Recommendations Update to a version of the Linux kernel newer than 6.4.0-rc6+.
