Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: KVM: VMX: Grab vmcs12 on CR8
interception update iff vCPU is in guest mode When updating CR8 intercepts, get vmcs12 if and only if the
vCPU is in guest mode so that a future change can have update CR8 intercepts during vCPU creation, without
running afoul of get_vmcs12()'s lockdep assertion. ------------[ cut here ]------------ debug_locks &&
