Overview

CVE-2024-53196 is a medium-severity vulnerability affecting linux linux_kernel. It was published on December 27, 2024 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

KVM: arm64: Don't retire aborted MMIO instruction

Returning an abort to the guest for an unsupported MMIO access is a

documented feature of the KVM UAPI. Nevertheless, it's clear that this

plumbing has seen limited testing, since userspace can trivially cause a

WARN in the MMIO return:
