CVE-2022-41841Public exploit

Application crash via null pointer dereference

Published Sep 30, 2022 · Updated May 20, 2025

NULL pointer dereference in Bento4 through 1.6.0-639 allows context-dependent attackers to crash mp42hevc with a crafted MP4 file. AP4_File::ParseStream reads through a null pointer while AP4_File constructs an object from attacker-controlled MP4 content. The victim must cause a local Bento4-based tool or application to parse the file, and the demonstrated consequence is process termination rather than data access or modification.
