hw: cpu: speculative execution bounds-check bypass

An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions a commonly used performance optimization. There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Variant...

Linux kernel denial of service vulnerability (CNVD-2018-06460)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A security vulnerability exists in the 'munlockpagevec' function in the mm/mlock.c file in Linux kernel versions prior to 4.11.4. A local attacker can exploit this...

Kernel: KVM: debug exception via syscall emulation

A flaw was found in the way the Linux KVM module processed the trap flagTF bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exceptionDB being raised in the guest stack. A user/process inside a guest could use this flaw to potentially escalate their privileges insi...
