SUSE CVE-2024-21980
Improper restriction of write operations in SNP firmware could allow a malicious hypervisor to potentially overwrite a guest's memory or UMC seed resulting in loss of confidentiality and integrity...
CVE-2024-21978
A flaw was found in the AMD firmware. This vulnerability allows a malicious hypervisor to read or overwrite guest memory, potentially leading to data leakage or data corruption. Mitigation Mitigation for this issue is either not available or the currently available options do not meet the Red Hat...
Undermining Integrity Features of SEV-SNP with Memory Aliasing
AMD ID: AMD-SB-3015 Potential Impact: Loss of Integrity Severity: Medium Summary A team of researchers has reported to AMD that it may be possible to modify serial presence detect SPD metadata to make an attached memory module appear larger than it is, potentially allowing an attacker to overwrit...
