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