Overview

CVE-2023-52654 is a high-severity vulnerability. It was published on May 14, 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:

io_uring/af_unix: disable sending io_uring over sockets

File reference cycles have caused lots of problems for io_uring

in the past, and it still doesn't work exactly right and races with

unix_stream_read_generic(). The safest fix would be to completely

disallow sending io_uring files via sockets via SCM_RIGHT, so there

are no possible cycles invloving registered files and thus rendering

SCM accounting on the io_uring side unnecessary.

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.
