Overview

CVE-2023-52732 is a critical-severity vulnerability. It was published on May 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:

ceph: blocklist the kclient when receiving corrupted snap trace

When received corrupted snap trace we don't know what exactly has

happened in MDS side. And we shouldn't continue IOs and metadatas

access to MDS, which may corrupt or get incorrect contents.

This patch will just block all the further IO/MDS requests

immediately and then evict the kclient itself.

The reason why we still need to evict the kclient just after

blocking all the further IOs is that the MDS could revoke the caps

faster.

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.
