CVE-2024-29780

Local stack-data disclosure via uninitialized buffer

Published Jun 13, 2024 · Updated Mar 18, 2025

Information disclosure in Google Android's hwbcc TA allows local users to read uninitialized stack data during privilege removal. hwbcc_ns_deprivilege in trusty/user/base/lib/hwbcc/client/hwbcc.c exposes stack contents because data used by the deprivileging path is not initialized before disclosure. Low execution privileges are required, no user interaction is needed, and the documented consequence is limited to local confidentiality loss.
