CVE-2024-46819

A flaw was found in the Linux kernel's drm/amdgpu component. A local attacker with low privileges could trigger a null pointer dereference by interacting with the nbio_v7_4 functionality when the ras_manager object is null. This could lead to a system crash, resulting in a denial of service.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To mitigate this issue, prevent the amdgpu kernel module from loading. This can be achieved by creating a modprobe configuration file. Note that this may impact graphics functionality if an AMD GPU is in use and requires a system reboot to take effect.

echo "blacklist amdgpu" | sudo tee /etc/modprobe.d/amdgpu-blacklist.conf
sudo dracut -f
sudo reboot
