Linux Kernel Security Vulnerabilities
The Linux kernel version 5.17 contains a security vulnerability. This vulnerability arises from the failure to forcibly refresh the vmcs02 MSR bitmap when the runtime eVMCS control is modified. As a result, it may lead to reads and writes of L0 TPR by L2 or L1 via the proxy...
kernel: KVM: x86: Don't (re)check L1 intercepts when completing userspace I/O
A flaw was found in the Kernel-based Virtual Machine KVM for x86. This vulnerability occurs when KVM incorrectly re-checks Level 1 L1 intercepts during the completion of userspace I/O emulation for a Level 2 L2 instruction. If the L1 or host userspace modifies I/O interception settings during thi...
