Description

This security bulletin contains information about 1 vulnerability.

1) Improper control of a resource through its lifetime (CVE-ID: CVE-2026-31573)

CWE-ID: CWE-664 - Improper control of a resource through its lifetime

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 improper memory section annotation in the hantro probe path when probing the driver as a module. A local user can trigger driver probe operations to cause a denial of service.

The issue occurs because data referenced from non-init code is freed after module initialization and later accessed during probe, including probe deferrals or unbind-bind cycles.

Remediation

Install update from vendor's website.
