SB2026102453 - Reachable assertion in Linux kernel iwlwifi mld driver

Description

This security bulletin contains information about 1 vulnerability.

1) Reachable assertion (CVE-ID: CVE-2026-98874)

CWE-ID: CWE-617 - Reachable Assertion

CVSSv4: 0 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:N]

The vulnerability allows a local privileged user to trigger an unintended kernel warning during system suspend.

The vulnerability exists due to a reachable assertion in the iwl_mld_wowlan_suspend() function of the Linux kernel's iwlwifi MLD driver when suspending with Wake on Wireless LAN configured while disconnected from a network and without network detection configured. A local privileged user can configure this combination and initiate suspend to trigger the WARN_ON() assertion despite the configuration being valid.

Remediation

Install update from vendor's website.
