Descriptions
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu/pm: Fix NULL pointer dereference when get power limit
Because powerplay_table initialization is skipped under
sriov case, We check and set default lower and upper OD
value if powerplay_table is NULL.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/amdgpu/pm: corrige la desreferencia del puntero NULL cuando se obtiene el límite de energía. Debido a que la inicialización de powerplay_table se omite en el caso sriov, verificamos y configuramos el valor OD inferior y superior predeterminado si powerplay_table es NULL.
