Overview

CVE-2024-50270 is a medium-severity vulnerability. It was published on November 19, 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:

mm/damon/core: avoid overflow in damon_feed_loop_next_input()

damon_feed_loop_next_input() is inefficient and fragile to overflows.

Specifically, 'score_goal_diff_bp' calculation can overflow when 'score'

is high. The calculation is actually unnecessary at all because 'goal' is

a constant of value 10,000. Calculation of 'compensation' is again

fragile to overflow. Final calculation of return value for under-achiving

case is again fragile to overflow when the current score is

under-achieving the target.

Add two corner cases handling at the beginning of the function to make the

body easier to read, and rewrite the body of the function to avoid

overflows and the unnecessary bp value calcuation.

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.

How can CyberStrike help with CVE-2024-50270?

CyberStrike is an open-source, AI-augmented pentesting engine.
