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

Description A flaw exists in the Linux kernel’s accel/amdxdna component where a crash can occur when destroying a suspended hardware context. This happens if a user space process issues an ioctl to destroy a hardware context that has already been automatically suspended, leading to a null pointer dereference because the mailbox channel pointer is NULL for the suspended context. The issue is addressed by checking the mailbox channel pointer in the aie2 destroy context() function before accessing it.

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