Descriptions
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Handle dml allocation failure to avoid crash
[Why]
In the case where a dml allocation fails for any reason, the
current state's dml contexts would no longer be valid. Then
subsequent calls dc_state_copy_internal would shallow copy
invalid memory and if the new state was released, a double
free would occur.
[How]
Reset dml pointers in new_state to NULL and avoid invalid
pointer
(cherry picked from commit bcafdc61529a48f6f06355d78eb41b3aeda5296c)
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amd/display: Controlar el error de asignación de dml para evitar un bloqueo [Por qué] En el caso de que una asignación de dml falle por cualquier motivo, los contextos dml del estado actual ya no serían válidos. Luego, las llamadas posteriores a dc_state_copy_internal realizarían una copia superficial de la memoria no válida y, si se liberara el nuevo estado, se produciría una doble liberación. [Cómo] Restablecer los punteros dml en new_state a NULL y evitar un puntero no válido (seleccionado de el commit bcafdc61529a48f6f06355d78eb41b3aeda5296c)
