NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-livepatch-5_14_21-150400_15_23-rt package and not the kernel-livepatch-5_14_21-150400_15_23-rt package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

A flaw was found in KVM. When calling the KVM_GET_DEBUGREGS ioctl, on 32-bit systems, there might be some uninitialized portions of the kvm_debugregs structure that could be copied to userspace, causing an information leak.
