Description
A flaw was found in the Linux kernel's Meson video decoder driver. When processing video format negotiation requests with an unsupported format on the output queue, the driver improperly falls back to a format that may not be supported by the platform format table. This issue leads to a NULL pointer dereference, allowing a local user to cause a kernel crash and resulting in a Denial of Service (DoS).
