CVE-2024-39484

5.5 · MEDIUM
Published Jul 5, 2024 linux CWE-770 EPSS 0.23% (13th pctl)

Overview

CVE-2024-39484 is a medium-severity vulnerability affecting linux linux_kernel. It was published on July 5, 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:

mmc: davinci: Don't strip remove function when driver is builtin

Using __exit for the remove function results in the remove callback being

discarded with CONFIG_MMC_DAVINCI=y. When such a device gets unbound (e.g.

using sysfs or hotplug), the driver is just removed without the cleanup

being performed. This results in resource leaks. Fix it by compiling in the

remove callback unconditionally.

This also fixes a W=1 modpost warning:

WARNING: modpost: drivers/mmc/host/davinci_mmc: section mismatch in

reference: davinci_mmcsd_driver+0x10 (section: .data) ->

davinci_mmcsd_remove (section: .exit.text)

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.
