Remote memory corruption via unterminated SSID name
Published Mar 5, 2020 · Updated Aug 4, 2024
Out-of-bounds write in Qualcomm Snapdragon WLAN drivers allows remote attackers to corrupt memory through a crafted SSID name. The WLAN host driver writes a terminating NULL character outside the SSID-name buffer because the terminator is placed after an invalid array index. Reachability requires affected WLAN hardware and driver code to process attacker-controlled wireless metadata; public sources establish no consequence beyond memory corruption.
