CVE-2024-36949: amd/amdkfd: sync all devices to wait all processes being evicted

In the Linux kernel, the following vulnerability has been resolved: amd/amdkfd: sync all devices to wait all processes being evicted If there are more than one device doing reset in parallel, the first device will call kfd_suspend_all_processes() to evict all processes on all devices, this call takes time to finish. other device will start reset and recover without waiting. if the process has not been evicted before doing recover, it will be restored, then caused page fault.

Security readout for executives and security teams

Plain-English summary

CVE-2024-36949 is a Linux kernel issue in AMD GPU compute handling. During simultaneous GPU device resets, processes may be restored before eviction completes, causing page faults. The main business risk appears to be system or workload instability on affected Linux systems using AMD GPU/KFD functionality.

Executive priority

Treat as a targeted infrastructure maintenance item. Prioritize GPU compute platforms and systems where instability affects production workloads. There is no source-supported evidence of active exploitation, but kernel fixes should be included in normal patch cycles.

Technical view

The flaw is in amd/amdkfd reset recovery synchronization. One device may start recovery while another is still evicting processes across devices via kfd_suspend_all_processes(). If recovery occurs before eviction finishes, a process can be restored prematurely and trigger a page fault. Kernel stable commits are referenced as the resolution.

Likely exposure

Exposure is most relevant to Linux systems with AMD GPU/KFD support, especially multi-GPU or GPU-compute environments where parallel device resets can occur. Distribution backports may change exposure, so version-only checks are insufficient.

Exploitation context

No active exploitation is indicated in the provided sources, and the CVE is not listed as KEV. The source material describes a race-condition stability issue, not a remote attack path. Required conditions and security impact are not fully characterized.

Researcher notes

The public record provides limited severity detail: no CVSS, CWE, or complete exploitability analysis. Assessment should focus on reproducing reset concurrency behavior safely, confirming patch presence, and mapping distro-specific affected builds. Avoid assuming all Linux systems are meaningfully exposed.

Mitigation direction

  • Apply Linux kernel updates containing the referenced stable fixes.
  • Check your Linux distribution advisory for backported fixes and package names.
  • Prioritize AMD GPU compute, multi-GPU, and reset-prone systems.
  • Schedule maintenance if kernel replacement requires reboot.

Validation and detection

  • Inventory Linux hosts using AMDGPU/KFD functionality.
  • Confirm installed kernels include the referenced stable commits or distro backports.
  • Review vendor changelogs for CVE-2024-36949 or amdkfd reset synchronization fixes.
  • Monitor affected systems for GPU reset, KFD eviction, and page fault events.
