What to do
AI-suggested
Until an official fix is available, avoid using USB-C docks with affected AMD GPU configurations or disable HDCP features if possible. Monitor Linux kernel updates and apply patches promptly once released.
Description
CVE-2025-37903 is a use-after-free vulnerability in the AMD GPU HDCP code within the Linux kernel. The flaw occurs because pointers to amdgpu_dm_connector objects are copied without incrementing reference counts, leading to dangling pointers when a USB-C dock is unplugged and then re-plugged. This results in a slab-use-after-free error that can cause kernel crashes or potentially allow code execution. The vulnerability is rated high severity with a CVSS score of 7.8. No specific affected versions or patches are detailed in the provided data.
