Overview

CVE-2024-47695 is a critical-severity vulnerability. It was published on October 21, 2024 and has a CVSS 3.1 base score of 9.8 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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

RDMA/rtrs-clt: Reset cid to con_num - 1 to stay in bounds

In the function init_conns(), after the create_con() and create_cm() for

loop if something fails. In the cleanup for loop after the destroy tag, we

access out of bound memory because cid is set to clt_path->s.con_num.

This commits resets the cid to clt_path->s.con_num - 1, to stay in bounds

in the cleanup loop later.

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.
