Overview

CVE-2023-52664 is a high-severity vulnerability. It was published on May 17, 2024 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. 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:

net: atlantic: eliminate double free in error handling logic

Driver has a logic leak in ring data allocation/free,

where aq_ring_free could be called multiple times on same ring,

if system is under stress and got memory allocation error.

Ring pointer was used as an indicator of failure, but this is

not correct since only ring data is allocated/deallocated.

Ring itself is an array member.

Changing ring allocation functions to return error code directly.

This simplifies error handling and eliminates aq_ring_free

on higher layer.

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.
