CVE-2019-14014Network attack vector

Memory corruption via unterminated source byte array

Published Jan 21, 2020 · Updated Aug 5, 2024

Buffer overflow in Qualcomm Snapdragon video components allows remote attackers to corrupt memory through malformed byte-array input. A source is read as a byte array without a terminating null byte, causing incorrect input to overrun the destination buffer. Network delivery requires no authentication or user interaction, but the closed-source record discloses neither the accepted input format nor a demonstrated outcome beyond memory corruption.
