Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/panfrost: Job should reference MMU not file_priv
For a while now it's been allowed for a MMU context to outlive it's
corresponding panfrost_priv, however the job structure still references
panfrost_priv to get hold of the MMU context. If panfrost_priv has been
freed this is a use-after-free which I've been able to trigger resulting
in a splat.
To fix this, drop the reference to panfrost_priv in the job structure
and add a direct reference to the MMU structure which is what's actually
needed.

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/panfrost: El trabajo debe hacer referencia a MMU, no a file_priv Desde hace un tiempo se ha permitido que un contexto MMU sobreviva a su panfrost_priv correspondiente, sin embargo, la estructura del trabajo a\u00fan hace referencia a panfrost_priv para obtener el contexto MMU. Si panfrost_priv se ha liberado, se trata de un use-after-free que he podido activar, lo que ha dado como resultado un splat. Para solucionar esto, elimine la referencia a panfrost_priv en la estructura del trabajo y agregue una referencia directa a la estructura MMU, que es lo que realmente se necesita."
