CVE-2020-3658Network attack vector

Memory disclosure and crash via corrupted sample tables

Published Jun 22, 2020 · Updated Aug 4, 2024

NULL pointer dereference in Qualcomm Snapdragon MP4 parsing allows remote attackers to expose memory and crash processing via a malformed clip. The closed-source parser processes corrupted sample-table atoms without ensuring that the resulting pointer is valid before dereferencing it. An attacker-controlled MP4 must reach an affected chipset; the published impacts are limited to memory disclosure and service interruption, with no reported data modification.
