Description
A flaw was found in the Linux kernel's mt76: mt7996 Wi-Fi driver. This vulnerability occurs because the driver does not properly validate the size of the default EEPROM (Electrically Erasable Programmable Read-Only Memory) firmware. A specially crafted, truncated EEPROM firmware file can cause the driver to read beyond its allocated buffer, potentially leading to information disclosure or a denial of service.
