CVE-2026-80935
Description
A flaw was found in the Linux kernel's Wi-Fi driver for MediaTek MT7996 devices. A malicious or malfunctioning Wi-Fi device can exploit improper validation of an EEPROM (Electrically Erasable Programmable Read-Only Memory) address during a copy operation. This can lead to an out-of-bounds write, which may result in memory corruption and potentially allow for arbitrary code execution.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
