Published Sep 18, 2024 linux CWE-476 EPSS 0.25% (16th pctl)

Overview

CVE-2024-46761 is a medium-severity vulnerability affecting linux linux_kernel. It was published on September 18, 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:

pci/hotplug/pnv_php: Fix hotplug driver crash on Powernv

The hotplug driver for powerpc (pci/hotplug/pnv_php.c) causes a kernel

crash when we try to hot-unplug/disable the PCIe switch/bridge from

the PHB.

The crash occurs because although the MSI data structure has been

released during disable/hot-unplug path and it has been assigned

with NULL, still during unregistration the code was again trying to

explicitly disable the MSI which causes the NULL pointer dereference and

kernel crash.

The patch fixes the check during unregistration path to prevent invoking

pci_disable_msi/msix() since its data structure is already freed.

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.
