AI-analyzed exploit summary This repository contains a functional exploit for CVE-2023-46813, targeting a vulnerability in SEV-SNP VMs. The exploit leverages MMIO memory manipulation to escalate privileges by swapping task credentials with those of the init process.
Description
An issue was discovered in the Linux kernel before 6.5.9, exploitable by local users with userspace access to MMIO registers. Incorrect access checking in the #VC handler and instruction emulation of the SEV-ES emulation of MMIO accesses could lead to arbitrary write access to kernel memory (and thus privilege escalation). This depends on a race condition through which userspace can replace an instruction before the #VC handler reads it.
