Overview

CVE-2026-53022 is a medium-severity vulnerability. It was published on June 24, 2026 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:

platform/x86: dell-wmi-sysman: bound enumeration string aggregation

populate_enum_data() aggregates firmware-provided value-modifier

and possible-value strings into fixed 512-byte struct members.

The current code bounds each individual source string but then

appends every string and separator with raw strcat() and no

remaining-space check.

Switch the aggregation loops to a bounded append helper and

reject enumeration packages whose combined strings do not fit

in the destination buffers.

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.
