CVE-2026-90377: wifi: mt76: fix RX data queuing of RRO 3.0

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 62aea1d45b524cde9e02d1e7f65d2c4fd60871b8, 86897f106669c07eea4c34b54c3268d448d41426, db4be207f3f6d8886f0b31f8c7db863a4b835ec1.

Low priority for now. Upgrade to Linux Linux 62aea1d45b524cde9e02d1e7f65d2c4fd60871b8, 86897f106669c07eea4c34b54c3268d448d41426, db4be207f3f6d8886f0b31f8c7db863a4b835ec1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: fix RX data queuing of RRO 3.0 For RRO 3.0, RX data released from a RRO data queue should be put to the indicator queue. The frames are processed and completed in the context of the indicator queue NAPI, which only polls skbs queued on the MT_RXQ_RRO_IND list; frames queued under the data queue id are left sitting on that list until the data queue NAPI happens to run, stalling and reordering RX data.

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.
