Descriptions

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

drm/amdgpu: fix gart.bo pin_count leak

gmc_v{9,10}_0_gart_disable() isn't called matched with
correspoding gart_enbale function in SRIOV case. This will
lead to gart.bo pin_count leak on driver unload.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/amdgpu: corrige la fuga de pin_count de gart.bo gmc_v{9,10}_0_gart_disable() no se llama y coincide con la función gart_enbale correspondiente en el caso SRIOV. Esto provocará una pérdida de pin_count de gart.bo al descargar el controlador.
