CVE-2026-53277

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.
