  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mt76: mt7915: bound the device EEPROM address before the EFUSE copy\n\nmt7915_mcu_get_eeprom() copies a fixed EFUSE block into the driver's\ndev-\u003emt76.eeprom.data buffer at the offset reported by the MCU response\n(res-\u003eaddr, a device-controlled __le32) without checking it against the\nbuffer size. A malicious or malfunctioning device can report an arbitrary\naddress and drive a 16-byte out-of-bounds write past eeprom.data.\n\nReject a response whose address would place the copy outside eeprom.data\nbefore deriving the destination pointer. Devices that echo the requested\nin-bounds offset are unaffected.",
