SUSE CVE-2021-29657

arch/x86/kvm/svm/nested.c in the Linux kernel before 5.11.12 has a use-after-free in which an AMD KVM guest can bypass access control on host OS MSRs when there are nested guests, aka CID-a58d9166a756. This occurs because of a TOCTOU race condition associated with a VMCB12 double fetch in...

x86: Cross-Thread Return Address Predictions

ISSUE DESCRIPTION It has been discovered that on some AMD CPUs, the RAS Return Address Stack, also called RAP - Return Address Predictor - in some AMD documentation, and RSB - Return Stack Buffer - in Intel terminology is dynamically partitioned between non-idle threads. This allows an attacker t...
