Descriptions

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

drm/msm: Fix null pointer dereference on pointer edp

The initialization of pointer dev dereferences pointer edp before
edp is null checked, so there is a potential null pointer deference
issue. Fix this by only dereferencing edp after edp has been null
checked.

Addresses-Coverity: ("Dereference before null check")

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/msm: corrige la desreferencia del puntero nulo en el puntero edp. La inicialización del puntero dev desreferencias del puntero edp antes de edp se marca como nula, por lo que existe un posible problema de deferencia del puntero nulo. Solucione este problema eliminando la referencia a edp únicamente después de que se haya marcado como nulo. Direcciones-Cobertura: ("Desreferencia antes de verificación nula")
