Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A null pointer dereference vulnerability has been resolved in the Linux kernel. The issue occurs in the nvme-fc module, specifically in the nvme fc io getuuid function. The nvme fc fcp op structure describing an AEN operation is initialized with a null request structure pointer. An FC LLDD may make a call to nvme fc io getuuid passing a pointer to an nvmefc fcp req for an AEN operation. To fix this issue, validation of the request structure pointer has been added before dereference.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
