CVE-2018-9463

Local privilege escalation via touchscreen bounds check

Published Dec 4, 2024 · Updated Dec 5, 2024

Out-of-bounds write in Google Android's Pixel touchscreen kernel driver allows local users to gain elevated privileges. The sw49408_irq_runtime_engine_debug function in touch_sw49408.c applies an incorrect bounds check and writes beyond the intended buffer. Exploitation requires System execution privileges and no user interaction, and successful abuse grants higher local privileges.
