Описание
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Fix smatch static checker warning
adev->gfx.imu.funcs could be NULL
A flaw was found in the drm/amdgpu driver of the Linux kernel. A local attacker could exploit this vulnerability by triggering a null pointer dereference. This could lead to a system crash, causing a denial of service (DoS) on the affected system.
Меры по смягчению последствий
To mitigate this issue, if AMD GPU hardware is not in use or its functionality is not critical, the amdgpu kernel module can be prevented from loading. This can be achieved by creating a blacklist entry for the module.
- Create a new configuration file:
echo "blacklist amdgpu" | sudo tee /etc/modprobe.d/amdgpu-blacklist.conf - Rebuild the initial ramdisk:
sudo dracut -f - Reboot the system for the changes to take effect:
sudo rebootThis mitigation may impact graphical performance or functionality if AMD GPU hardware is actively used. A system reboot is required for the changes to take effect.
