CVE-2024-32916

Local information disclosure via uninitialized histogram data

Published Jun 13, 2024 · Updated Dec 6, 2024

Information disclosure in the Android kernel ACPM component allows local users to read uninitialized data through fvp_freq_histogram_init. The fvp_freq_histogram_init function in fvp.c exposes data that the initialization path leaves unset when preparing a frequency histogram. Local access is required, but no additional execution privileges or user interaction are needed; the disclosed data is not publicly characterized.
