About this tag
CVE-2024-53114 is a Linux kernel vulnerability affecting AMD Zen4 client processors. The flaw involves certain Zen4 client SoCs incorrectly advertising support for virtualized VMLOAD/VMSAVE instructions. When these instructions are used during virtualization workloads, the host system can experience random reboots. A kernel patch addresses this by clearing the advertised capability for affected models, preventing the instability. Administrators running virtualized workloads, particularly nested VMs or environments exposing hardware virtualization features to guests, should apply the patch to avoid unpredictable host resets. The issue is specific to Linux and AMD Zen4 client CPUs, not Windows or Microsoft systems.
  1. Linux Kernel Patch Shields Zen4 Client CPUs from VMLOAD VMSAVE Reboot Risk

    A small-but-critical Linux kernel change has quietly landed that protects systems running AMD Zen4 client processors from a surprising stability hazard: several Zen4 client SoCs were advertising support for virtualized VMLOAD/VMSAVE instructions, and when those instructions were actually used...
