Overview

CVE-2024-50192 is a medium-severity vulnerability affecting linux linux_kernel. It was published on November 8, 2024 and has a CVSS 3.1 base score of 4.7 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 4.7, 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:

irqchip/gic-v4: Don't allow a VMOVP on a dying VPE

Kunkun Jiang reported that there is a small window of opportunity for

userspace to force a change of affinity for a VPE while the VPE has already

been unmapped, but the corresponding doorbell interrupt still visible in

/proc/irq/.

Plug the race by checking the value of vmapp_count, which tracks whether

the VPE is mapped ot not, and returning an error in this case.

This involves making vmapp_count common to both GICv4.1 and its v4.0

ancestor.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. 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.
