Published Sep 15, 2025CWE-908EPSS 0.16%

Overview

CVE-2023-53165 is a medium-severity vulnerability. It was published on September 15, 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:

udf: Fix uninitialized array access for some pathnames

For filenames that begin with . and are between 2 and 5 characters long,

UDF charset conversion code would read uninitialized memory in the

output buffer. The only practical impact is that the name may be prepended a

"unification hash" when it is not actually needed but still it is good

to fix this.

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.
