Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A vulnerability in the Linux kernel has been resolved, related to the KVM (Kernel-based Virtual Machine) component. The issue occurs when the target vCPU is not fully online before its index is clamped in the
kvm get vcpu() function. This can lead to KVM returning vCPU0 instead of NULL, potentially causing problems if userspace or the guest is buggy or misbehaving. The bug can trigger a use-after-free if vCPU0 is dereferenced and vCPU creation fails, resulting in a crash.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
