CVE-2022-40280Network attack vector

Service interruption via unreleased SQLite handles

Published Sep 8, 2022 · Updated Aug 3, 2024

Resource exhaustion in Samsung TizenRT through 3.0_GBM and 3.1_PRE allows remote attackers to interrupt service through createDB calls. The createDB function calls sqlite3_open_v2 but omits sqlite3_close, leaving each returned database connection handle and its resources unreleased. Network reachability is sufficient and authentication is not required; resource exhaustion affects availability without reported data access or modification.
