Remote memory corruption via unchecked copy length
Published Feb 9, 2023 · Updated Aug 3, 2024
Improper input validation in Qualcomm Snapdragon modem firmware allows remote attackers to corrupt memory via crafted network input. Proprietary modem code copies attacker-controlled input into memory without adequately checking its length, permitting an out-of-bounds write. A network-reachable modem requires no authentication or user interaction, and triggering the flaw corrupts modem memory.
