SUSE-SU-2023:4654-1 Security update for kernel-firmware

This update for kernel-firmware fixes the following issues: Update AMD ucode to 20231030 bsc1215831: - CVE-2022-23820: Failure to validate the AMD SMM communication buffer may allow an attacker to corrupt the SMRAM potentially leading to arbitrary code execution. - CVE-2021-46774: Insufficient...

The vulnerability of the INVD processor instruction for virtual machines running on AMD-processor-based servers allows a hacker to cause a loss of memory integrity in the guest virtual machine.

The vulnerability of the INVD processor instruction for virtual machines running on AMD-processor servers is related to the loss or omission of information. Exploiting this vulnerability can allow a malicious actor to cause the guest virtual machine’s memory to be compromised...

SUSE CVE-2023-20592

Improper or unexpected behavior of the INVD instruction in some AMD CPUs may allow an attacker with a malicious hypervisor to affect cache line write-back behavior of the CPU leading to a potential loss of guest virtual machine VM memory integrity...

Memory Integrity Loss
