Description
A flaw was found in the Linux kernel's p54 Wi-Fi driver. The driver fails to verify that an entire interface record fits within the buffer boundaries when parsing EEPROM (Electrically Erasable Programmable Read-Only Memory) data. An attacker capable of attaching a crafted wireless device or supplying malformed data can exploit this condition to trigger an out-of-bounds memory read. This flaw can lead to sensitive information disclosure or cause a system crash, resulting in a Denial of Service (DoS).
