CVE-2024-47018

Local information disclosure via ACPM buffer over-read

Published Oct 25, 2024 · Updated Oct 25, 2024

Out-of-bounds read in Android's ACPM kernel component allows local users to disclose memory through malformed sequence data. pmucal_rae_handle_seq_int in flexpmu_cal_rae.c reads beyond its intended buffer while handling a sequence, exposing adjacent kernel memory. Exploitation requires local low-privileged access on an affected Pixel device, needs no user interaction, and is limited to information disclosure.
