Overview

CVE-2023-53353 is a medium-severity vulnerability. It was published on September 17, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. 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:

accel/habanalabs: postpone mem_mgr IDR destruction to hpriv_release()

The memory manager IDR is currently destroyed when user releases the

file descriptor.

However, at this point the user context might be still held, and memory

buffers might be still in use.

Later on, calls to release those buffers will fail due to not finding

their handles in the IDR, leading to a memory leak.

To avoid this leak, split the IDR destruction from the memory manager

fini, and postpone it to hpriv_release() when there is no user context

and no buffers are used.

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.
