Summary
The Wi-Fi NPU firmware contains an out-of-bounds write caused by an incorrect bounds check. An attacker with low-privilege access from an adjacent network can trigger it without any user interaction, causing a denial of service.

Questions about CVE-2026-89142
Is CVE-2026-89142 being exploited?
It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.Source: cve.now feed data
