Local denial of service via unchecked apipe write
Published May 9, 2023 · Updated Jan 28, 2025
Out-of-bounds write in the apipe driver on UNISOC Android 11 and Android 12 chipsets allows local users to interrupt device service. The driver writes beyond a memory buffer because it omits a bounds check before the write operation. Exploitation requires local System execution privileges; the documented consequence is service interruption, not data disclosure or code execution.
