CVE-2026-80933
7.8
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7996: validate default EEPROM firmware size
The default EEPROM firmware is parsed and copied as a full EEPROM without checking its length. A truncated file can make the driver read beyond the firmware buffer during variant validation or the fallback copy.
Reject files shorter than MT7996_EEPROM_SIZE before parsing or copying the firmware.
