CVE-2025-27701

Local information disclosure via unchecked NULL dereference

Published May 27, 2025 · Updated Sep 4, 2025

NULL pointer dereference in the Android kernel allows local users to disclose memory through an out-of-bounds read in process_crypto_cmd. slice_map_array can leave ptrs[i] set to NULL, and process_crypto_cmd later dereferences the entry without checking it. Exploitation requires low-privilege local access and no user interaction; the bounded impact is memory disclosure, with a temporary service interruption also reported.
