  "details": "In the Linux kernel, the following vulnerability has been resolved:  wifi: mt76: mt7996: bound the device EEPROM address before the EFUSE copy  mt7996_mcu_get_eeprom() derives the destination of the EFUSE/EXT block copy from the address reported by the MCU response (event-\u003eaddr, a device-controlled __le32) and clamps only the copy length, never the destination offset into dev-\u003emt76.eeprom.data. A malicious or malfunctioning device can report an arbitrary address and drive an out-of-bounds write of up to MT7996_EXT_EEPROM_BLOCK_SIZE bytes past eeprom.data.  Reject a response whose address would place the copy outside eeprom.data before deriving the destination pointer. Devices that echo the requested in-bounds offset are unaffected.",
