CVE-2026-80933

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.
