It was discovered that some AMD processors did not properly perform Reverse
Map Table (RMP) checks when the IOMMU accessed certain host buffers. A
local attacker with hypervisor access could possibly use this to trigger an
out-of-bounds condition and compromise the integrity of SEV-SNP guest
memory. (CVE-2023-20585)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
