- 7.8 HIGH — CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Description
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.
