Description
A flaw was found in the Linux kernel's AMD XDNA driver. A local user with access to the accelerator device node can trigger a Denial of Service (DoS) by submitting an empty command chain with a zero command count. Because the driver fails to properly validate the command count, it processes an empty buffer and performs an out-of-bounds memory read, leading to a system crash.
