Descriptions

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: Fix the null pointer when load rlc firmware

If the RLC firmware is invalid because of wrong header size,
the pointer to the rlc firmware is released in function
amdgpu_ucode_request. There will be a null pointer error
in subsequent use. So skip validation to fix it.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/amdgpu: corrige el puntero nulo al cargar el firmware rlc. Si el firmware RLC no es válido debido a un tamaño de encabezado incorrecto, el puntero al firmware rlc se libera en la función amdgpu_ucode_request. Habrá un error de puntero nulo en el uso posterior. Así que omita la validación para solucionarlo.

A vulnerability was found in the drm/amdgpu driver of Linux Kernel, causing null pointer dereference when attempting to load RLC (Run-Length Coding) firmware. This issue arises if the firmware has an incorrect header size, causing premature release of the firmware pointer in amdgpu_ucode_request(), subsequently attempts to use the nullified pointer result in errors.
