Published Dec 27, 2024 linux CWE-401 EPSS 0.20% (10th pctl) CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Overview

CVE-2024-53236 is a medium-severity vulnerability affecting linux linux_kernel. It was published on December 27, 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:

xsk: Free skb when TX metadata options are invalid

When a new skb is allocated for transmitting an xsk descriptor, i.e., for

every non-multibuf descriptor or the first frag of a multibuf descriptor,

but the descriptor is later found to have invalid options set for the TX

metadata, the new skb is never freed. This can leak skbs until the send

buffer is full which makes sending more packets impossible.

Fix this by freeing the skb in the error path if we are currently dealing

with the first frag, i.e., an skb allocated in this iteration of

xsk_build_skb.

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.
