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...

Design/Logic Flaw

Arm provides multiple helpers to clean & invalidate the cache for a given region. This is, for instance, used when allocating guest memory to ensure any writes such as the ones during scrubbing have reached memory before handing over the page to a guest. Unfortunately, the arithmetics in the...

CVE-2023-46837 arm32: The cache may not be properly cleaned/invalidated (take two)

Arm provides multiple helpers to clean & invalidate the cache for a given region. This is, for instance, used when allocating guest memory to ensure any writes such as the ones during scrubbing have reached memory before handing over the page to a guest. Unfortunately, the arithmetics in the...
