Vulnerability CVE-2019-19067


Published: 2019-11-18   Modified: 2019-11-19

Description:
** DISPUTED ** 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.

Type:

CWE-400
