hw: cpu: Intel: Post-barrier Return Stack Buffer Predictions

A flaw was found in hw. In certain processors with Intel's Enhanced Indirect Branch Restricted Speculation eIBRS capabilities, soon after VM exit or IBPB command event, the linear address following the most recent near CALL instruction prior to a VM exit may be used as the Return Stack Buffer RSB...

kernel: KVM: NULL pointer dereference in kvm_dirty_ring_push in virt/kvm/dirty_ring.c

A NULL pointer dereference issue was found in KVM when releasing a vCPU with dirty ring support enabled. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service...

kernel: KVM: cmpxchg_gpte can write to pfns outside the userspace region

A flaw was found in KVM. When updating a guest's page table entry, vmpgoff was improperly used as the offset to get the page's pfn. As vaddr and vmpgoff are controllable by user-mode processes, this flaw allows unprivileged local users on the host to write outside the userspace region and...

Vagrant Synced Folder Vagrantfile Breakout Exploit

This Metasploit module exploits a default Vagrant synced folder shared folder to append a Ruby payload to the Vagrant project Vagrantfile config file. By default, unless a Vagrant project explicitly disables shared folders, Vagrant mounts the project directory on the host as a writable vagrant...

CVE-2022-39354

SputnikVM, also called evm, is a Rust implementation of Ethereum Virtual Machine. A custom stateful precompile can use the isstatic parameter to determine if the call is executed in a static context via STATICCALL, and thus decide if stateful operations should be done. Prior to version 0.36.0, th...

kernel: KVM: VMX: Prevent RSB underflow before vmenter

In the Linux kernel, the following vulnerability has been resolved: KVM: VMX: Prevent RSB underflow before vmenter On VMX, there are some balanced returns between the time the guest's SPECCTRL value is written, and the vmenter. Balanced returns matched by a preceding call are usually ok, but it's...
