Memory corruption via unchecked DTLS message copy
Published Mar 4, 2024 · Updated Aug 26, 2024
Out-of-bounds write in Qualcomm Data Modem firmware allows remote attackers to corrupt memory during a crafted DTLS handshake. While verifying a hello-verify message, the modem copies attacker-controlled handshake data without checking its size. No privileges or user interaction are required; Qualcomm reports confidentiality, integrity, and availability impact but does not disclose the exact corruption outcome.
