Overview

CVE-2024-47749 is a high-severity vulnerability. It was published on October 21, 2024 and has a CVSS 3.1 base score of 7.5 (HIGH).

Technical description

In the Linux kernel, the following vulnerability has been resolved:

RDMA/cxgb4: Added NULL check for lookup_atid

The lookup_atid() function can return NULL if the ATID is

invalid or does not exist in the identifier table, which

could lead to dereferencing a null pointer without a

check in the `act_establish()` and `act_open_rpl()` functions.

Add a NULL check to prevent null pointer dereferencing.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

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.
