Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
In the arm64 KVM implementation, the functions
walk s1() and kvm walk nested s2() require the kvm->srcu lock to be held to prevent issues during memslot changes. However, kvm at s12() and kvm find s1 desc level() call these walkers without acquiring the necessary lock, which can lead to instability during fault injection and AT emulation.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
