Description
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
Affected configurations
• linux linux kernel (< 5.3.8)
• canonical ubuntu linux 18.04
• canonical ubuntu linux 19.04
• canonical ubuntu linux 19.10
• opensuse leap 15.1
