Overview

CVE-2024-46707 is a medium-severity vulnerability. It was published on September 13, 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: Make ICC_*SGI*_EL1 undef in the absence of a vGICv3

On a system with a GICv3, if a guest hasn't been configured with

GICv3 and that the host is not capable of GICv2 emulation,

a write to any of the ICC_*SGI*_EL1 registers is trapped to EL2.

We therefore try to emulate the SGI access, only to hit a NULL

pointer as no private interrupt is allocated (no GIC, remember?).

The obvious fix is to give the guest what it deserves, in the

shape of a UNDEF exception.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
