Local privilege escalation affects AMD Zen 2-based processors (Ryzen 3000/4000/5000 series, Threadripper PRO 3000 WX, EPYC 7002, and various embedded parts) where improper isolation of shared resources in the CPU operation cache lets a low-privileged attacker corrupt instructions executed at a higher privilege level. Reported by AMD and tracked as AMD-SB-7052 (with parallel Xen XSA-490 and Linux/OS-vendor advisories), it carries a CVSS 4.0 base score of 7.3 but requires local access and high attack complexity. There is no public exploit identified at time of analysis, and the EPSS probability is negligible at 0.01% (2nd percentile).
Improper isolation of GPU HW register space could allow a privileged attacker in malicious Guest Virtual Machine (VM) to perform unauthorized access to specific victim range of GPU MMIO register. Rated medium severity (CVSS 6.8), this vulnerability is low attack complexity. No vendor patch available.
Improper isolation of shared resources on a system on a chip by a malicious local attacker with high privileges could potentially lead to a partial loss of integrity.
Improper isolation of shared resources on System-on-a-chip (SOC) could a privileged attacker to tamper with the contents of the PSP reserved DRAM region potentially resulting in loss of. Rated high severity (CVSS 7.2). No vendor patch available.
