USN-8888-2: Linux kernel (Azure) 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...

USN-8888-2 linux-azure-7.0, linux-azure-fde-7.0 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...

Linux kernel Memory Management Heap Buffer Overflow DoS

The vulnerability of the unmergeandremoveallrmapitems function in the mm/ksm.c module of the Linux kernel’s memory management subsystem is related to pointer manipulation. Exploiting this vulnerability could allow an attacker to trigger a system failure...
