CVE-2024-47032

Local privilege escalation via LWIS heap overflow

Published Jan 3, 2025 · Updated Jan 3, 2025

Heap buffer overflow in the Android LWIS kernel driver allows local users to escalate privileges through a crafted IOCTL transaction. construct_transaction_from_cmd in lwis_ioctl.c writes beyond a heap allocation while constructing a transaction from an untrusted command. Low-privileged local access to an affected Pixel device is required; exploitation needs no user interaction and grants elevated privileges.
