Descriptions

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

dm vdo: don't refer to dedupe_context after releasing it

Clear the dedupe_context pointer in a data_vio whenever ownership of
the context is lost, so that vdo can't examine it accidentally.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: dm vdo: no hacer referencia a dedupe_context después de liberarlo. Borre el puntero dedupe_context en un data_vio siempre que se pierda la propiedad del contexto, de modo que vdo no pueda examinarlo accidentalmente.
