Overview

CVE-2026-97569 is a known-severity vulnerability. It was published on September 25, 2026.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

bnxt_en: Prevent queue stop with deferred completions

When the driver receives a burst of packets, it can mark a BD with the

NO_CMPL bit to defer completions. The expectation is that the last

packet in the ring will have this bit unset and the completion generated

by that packet will cleanup that packet and the ones preceding it. This

helps to reduce the number of completions fired.

The suppressed completions are controlled by the driver and the number

of packets with suppressed completions scales with the size of the ring.

SW USO packets, on the other hand, have an upper bound on the maximum

number of BDs which can be consumed which does not scale with the ring

size.

So, for small rings it is possible that: a burst of packets is handed to

the driver, the driver defers completions for all of the packets because

the number of free descriptors stays above the threshold in the driver.

Then, a USO packet arrives, but t

How can CyberStrike help with CVE-2026-97569?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-97569 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
