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.

Linux DRM Ioctl Developed By AMD Being Disabled Following Ongoing Security Issue Written by Michael Larabel in Linux Kernel on 5 June 2026 at 08:52 PM EDT. Add A Comment It's unfortunately another busy week in the Linux 7.1 kernel space with not everything slowing down so well, late in the cycle and leading to the upcoming 7.1 stable release. This week's DRM pull request of kernel graphics/accelerator drivers is again heavy on fixes and also ends up disabling an ioctl interface given ongoing security concerns from that code merged last year.
