CVE-2023-1998 Spectre v2 SMT mitigations problem in Linux kernel

The Linux kernel allows userspace processes to enable mitigations by calling prctl with PRSETSPECULATIONCTRL which disables the speculation feature as well as by using seccomp. We had noticed that on VMs of at least one major cloud provider, the kernel still left the victim process exposed to...

CVE-2023-1998

CVE-2023-1998 affects the Linux kernel. Root cause: when using legacy IBRS, the IBRS bit is cleared on returning to userspace, disabling implicit STIBP and leaving some spectre-BTI protections ineffective; attackers on a local machine could exploit cross-thread branch target injection despite mit...
