Description

A flaw was found in the Linux kernel's accel/amdxdna component. An unexpected firmware error during message handling can cause a critical communication variable (mgmt_chann) to be set to NULL. This can lead to a NULL pointer dereference when the system attempts to stop hardware operations, resulting in a Denial of Service (DoS) that crashes the system.

Mitigation

No mitigation is specified in collected source.
