Description

This security bulletin contains information about 1 vulnerability.


1) Stack-based buffer overflow (CVE-ID: CVE-2026-53022)

CWE-ID: CWE-121 - Stack-based buffer overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to a stack-based buffer overflow in populate_enum_data() in the dell-wmi-sysman enumeration attribute handler when aggregating firmware-provided enumeration strings. A local user can provide crafted enumeration data to overflow fixed-size destination buffers and cause a denial of service.

The issue affects aggregation of value-modifier and possible-value strings into fixed 512-byte structure members.
