Описание
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Fix out-of-bounds read of df_v1_7_channel_number
Check the fb_channel_number range to avoid the array out-of-bounds
read error
A flaw was found in the drm/amdgpu component of the Linux kernel. An improper range check of the fb_channel_number could allow a local attacker to perform an out-of-bounds read. This could lead to information disclosure or a denial of service (DoS).
Меры по смягчению последствий
To mitigate this issue, prevent the amdgpu kernel module from loading. This can be achieved by creating a modprobe configuration file.
- Create a file named
/etc/modprobe.d/disable-amdgpu.confwith the following content:
- Regenerate the initramfs to apply the changes:
- Reboot the system for the changes to take effect.
Warning: Blacklisting the
amdgpumodule will disable AMD graphics functionality, potentially impacting system display and performance.
