CVE-2025-29943

CVE-2025-29943 : AMD CPUs (Zen 1–Zen 5; EPYC) contain a hardware/microarchitectural issue where an admin-privileged host can manipulate the CPU pipeline configuration, potentially corrupting the stack pointer inside a SEV-SNP guest. A PoC titled “StackWarp” demonstrates exploitation by a hypervis...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: x86/kvm: Forces the legacy PCI hole to be mapped as UC when overriding MTRRs for TDX/SNP. When running as an SNP or TDX guest under KVM, the legacy PCI hole—that is, the memory between Top of Lower Usable DRAM and 4 GiB—is forced...
