Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
wifi: mt76: mt7915: bound the device EEPROM address before the EFUSE copy<br />
<br />
mt7915_mcu_get_eeprom() copies a fixed EFUSE block into the driver&#39;s<br />
dev->mt76.eeprom.data buffer at the offset reported by the MCU response<br />
(res->addr, a device-controlled __le32) without checking it against the<br />
buffer size. A malicious or malfunctioning device can report an arbitrary<br />
address and drive a 16-byte out-of-bounds write past 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.
