USN-9091-1: Linux kernel (NVIDIA Tegra) vulnerabilities
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...
