SB20260812150 - Improper Initialization in Linux kernel broadcom bnxt driver

Description

This security bulletin contains information about 1 vulnerability.

1) Improper Initialization (CVE-ID: CVE-2026-68375)

CWE-ID: CWE-665 - Improper Initialization

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 initialization in bnxt_aux_devices_init() and the bnxt_aux_dev_release() release callback when unwinding errors after auxiliary_device_init(). A local user can trigger an allocation failure during auxiliary device initialization to cause a denial of service.

The issue arises because the release callback may dereference or clear partially initialized state.

Remediation

Install update from vendor's website.
