Description

A flaw was found in the Linux kernel's Airoha QDMA driver. This vulnerability occurs when the of_reserved_mem_lookup() function returns a NULL pointer, indicating that a referenced reserved memory region is not found. The driver then attempts to dereference this NULL pointer, leading to a kernel NULL pointer dereference. This can result in a system crash, causing a Denial of Service (DoS) for an affected system.

Mitigation

No mitigation is specified in collected source.
