CVE-2026-90101: bnxt_en: Fix call to hardware monitoring event handler

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.20% (FIRST EPSS).
  • Fixed version: Linux Linux 001ff5d8e68aacd91768b824b930dd7e68db6688, 622d698df4239fef3e0eb51fe59f4198f957f28a, b17907ef665bc76a495a8f909f74656d3f32b7a2.

Low priority for now. Upgrade to Linux Linux 001ff5d8e68aacd91768b824b930dd7e68db6688, 622d698df4239fef3e0eb51fe59f4198f957f28a, b17907ef665bc76a495a8f909f74656d3f32b7a2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Fix call to hardware monitoring event handler The first parameter of hwmon_notify_event() is supposed to be the hardware monitoring device. The bnxt driver calls it with the platform device as first parameter instead. This API break results in undefined behavior and may result in a crash. Pass the hardware monitoring device as parameter instead to fix the problem.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
