Description

A flaw was found in the Linux kernel's accel/amdxdna module. During error handling in the aie2_create_context() function, the aie_destroy_context() function can be called when a mailbox channel pointer is unexpectedly null. This can lead to a NULL pointer dereference, potentially causing a system crash and resulting in a Denial of Service (DoS).

Mitigation

No mitigation is specified in collected source.
