Overview

CVE-2023-53047 is a high-severity vulnerability. It was published on May 2, 2025 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:

tee: amdtee: fix race condition in amdtee_open_session

There is a potential race condition in amdtee_open_session that may

lead to use-after-free. For instance, in amdtee_open_session() after

sess->sess_mask is set, and before setting:

sess->session_info[i] = session_info;

if amdtee_close_session() closes this same session, then 'sess' data

structure will be released, causing kernel panic when 'sess' is

accessed within amdtee_open_session().

The solution is to set the bit sess->sess_mask as the last step in

amdtee_open_session().

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.
