Overview

CVE-2024-49955 is a medium-severity vulnerability. It was published on October 21, 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:

ACPI: battery: Fix possible crash when unregistering a battery hook

When a battery hook returns an error when adding a new battery, then

the battery hook is automatically unregistered.

However the battery hook provider cannot know that, so it will later

call battery_hook_unregister() on the already unregistered battery

hook, resulting in a crash.

Fix this by using the list head to mark already unregistered battery

hooks as already being unregistered so that they can be ignored by

battery_hook_unregister().

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.
