CVE-2023-0045

A flaw was found in the Linux kernel. This issue occurs due to a failure mitigating the Spectre-BTI attack using the kernel API, as IBPB is not issued during the syscall until the next schedule, leaving the system vulnerable. Mitigation For user-mode applications, a usleep after the prctl call wi...

CVE-2022-2196

A flaw was found in the KVM's Intel nested virtualization feature nVMX. Since L1 and L2 shared branch prediction modes guest-user and guest-kernel, KVM did not protect indirect branches in L1 from steering by a malicious agent in L2. This could allow a malicious nested guest to carry out Spectre ...
