A vulnerability in the Linux kernel's KVM subsystem for ARM64 architecture was resolved. The issue involved the improper handling of ESR_EL2 register writes for injected nested SError exceptions, causing stale syndrome information to be observed by guest L2 hypervisors. This flaw affected specific Linux kernel versions and could impact nested virtualization environments. The vulnerability has been addressed with a patch that ensures ESR_EL2 is correctly written for SError exceptions.
