Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/v3d: Se corrige la desreferenciación del puntero nulo del puntero perfmon. En el improbable caso de que el puntero perfmon sea nulo, la ruta de retorno WARN_ON se produce después de que el puntero ya haya sido desreferenciado. Solucione esto desreferenciando perfmon solo después de que se haya comprobado que es nulo.
