CVE-2024-53114: x86/CPU/AMD: Clear virtualized VMLOAD/VMSAVE on Zen4 client
First published: Mon Dec 02 2024(Updated: )
In the Linux kernel, the following vulnerability has been resolved: x86/CPU/AMD: Clear virtualized VMLOAD/VMSAVE on Zen4 client A number of Zen4 client SoCs advertise the ability to use virtualized VMLOAD/VMSAVE, but using these instructions is reported to be a cause of a random host reboot. These instructions aren't intended to be advertised on Zen4 client so clear the capability.
