CVE-2026-68375 — bnxt_en: Handle partially initialized auxiliary devices

In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Handle partially initialized auxiliary devices bnxt_aux_devices_init() calls auxiliary_device_init() before all fields used by bnxt_aux_dev_release() are initialized. After auxiliary_device_init() succeeds, later errors must unwind with auxiliary_device_uninit(), which invokes the release callback. The release callback assumes that aux_priv->id, aux_priv->edev, edev->net and edev->ulp_tbl are all populated. If allocation fails after auxiliary_device_init(), the release path can otherwise dereference or clear partially initialized state. Allocate and attach the bnxt_en_dev and ULP table before calling auxiliary_device_init(), so the release callback only sees a fully initialized auxiliary private object. If auxiliary_device_init() itself fails, free those allocations directly because device_initialize() has not run and the release callback will not be invoked. This issue was found by a static analysis checker and confirmed by manual source review.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

No scoring signals.

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Linux Linux).
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
