This vulnerability allows a malicious or malfunctioning Wi-Fi device to provide an invalid memory address. This can cause the driver to write data beyond its allocated memory, leading to an out-of-bounds write. Such memory corruption could potentially compromise system stability or allow for unauthorized code execution.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · updated 2026-09-14 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-80937.json)\n\n**kernel: wifi: mt76: mt7915: bound the device EEPROM address before the EFUSE copy** — rated Moderate by Red Hat.
