kernel: KVM: s390: pv: fix index value of replaced ASCE

In the Linux kernel, the following vulnerability has been resolved: KVM: s390: pv: fix index value of replaced ASCE The index field of the struct page corresponding to a guest ASCE should be 0. When replacing the ASCE in s390replaceasce, the index of the new ASCE should also be set to 0. Having t...

hw: amd: INVD instruction may lead to a loss of SEV-ES guest machine memory integrity problem

A flaw was found in some of AMD CPU's due to improper or unexpected behavior of the INVD. This issue may allow an attacker with a malicious hypervisor to affect cache line write-back behavior of the CPU, potentially leading to a loss of guest virtual machine VM memory integrity...
