Important: kernel

Issue Overview: AMD recommends using a software mitigation for this issue, which the kernel is enabling by default. The Linux kernel will use the generic retpoline software mitigation, instead of the specialized AMD one, on AMD instances 5a. This is done by default, and no administrator action is...

x86: speculative vulnerability in 32bit SYSCALL path

ISSUE DESCRIPTION Due to an oversight in the very original Spectre/Meltdown security work XSA-254, one entrypath performs its speculation-safety actions too late. In some configurations, there is an unprotected RET instruction which can be attacked with a variety of speculative attacks. IMPACT An...

Important: kernel

Issue Overview: A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks. L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after running L2 due to KVM L0 advertising eIBRS support to L1. An attacker at L...
