Descriptions
Four memory leaks in the acp_hw_init() function in drivers/gpu/drm/amd/amdgpu/amdgpu_acp.c in the Linux kernel before 5.3.8 allow attackers to cause a denial of service (memory consumption) by triggering mfd_add_hotplug_devices() or pm_genpd_add_device() failures, aka CID-57be09c6e874. NOTE: third parties dispute the relevance of this because the attacker must already have privileges for module loading
** EN DISPUTA ** Cuatro pérdidas de memoria en la función acp_hw_init() en el archivo drivers/gpu/drm/amd/amdgpu/amdgpu_acp.c en el kernel de Linux versiones anteriores a la versión 5.3.8, permiten a atacantes causar una denegación de servicio (consumo de memoria) al desencadenar fallos de la función mfd_add_hotplug_devices() o pm_genpd_add_device(), también se conoce como CID-57be09c6e874. NOTA: terceros discuten la relevancia de esto porque el atacante ya debe tener privilegios para cargar el módulo.
A flaw was found in the Linux kernel. The acp_hw_init function fails to cleanup resources properly. A local attacker can induce an error condition to crash the system. The highest threat from this vulnerability is to system availability.
