Description

This security bulletin contains information about 1 vulnerability.


1) Incomplete cleanup (CVE-ID: CVE-2026-72171)

CWE-ID: CWE-459 - Incomplete cleanup

CVSSv4: 6.8 [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]


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

The vulnerability exists due to improper cleanup in register_device() in the slram driver when handling device registration failures. A local user can trigger allocation or registration failures to cause a denial of service.

The issue occurs after a partially initialized entry has already been linked into the global device list, and a later cleanup can dereference or free invalid state from that failed entry.
