• Severity: medium (CVSS 4.4 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.5% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2019-11-18 · updated 2026-06-17
• Weakness: CWE-401

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

• Canonical Ubuntu Linux: 18.04, 19.04, 19.10
• Linux kernel: before 5.3.8 — fixed in 5.3.8
• openSUSE Leap: 15.1

How to fix

Upgrade to a fixed version: Linux kernel 5.3.8. Check the vendor advisory for mitigations.
