Linux DRM Ioctl Developed By AMD Being Disabled Following Ongoing Security Issue
AMD's Linux DRM ioctl has been disabled due to ongoing security issues. The ioctl, which was intended for use in the Checkpoint and Restore in User-Space (CRIU) initiative, has faced multiple attempts to fix its vulnerabilities. The decision to disable it comes after a series of failed fixes and concerns about its safety in the kernel environment.
- ▪The ioctl drm_gem_change_handle_ioctl() was introduced by AMD engineers for CRIU but has been disabled due to security vulnerabilities.
- ▪A security vulnerability identified as CVE-2026-23149 allowed user-space to trigger kernel warnings using the ioctl.
- ▪Multiple attempts to fix the ioctl have failed, leading to the decision to disable it until proper tests can be developed.
