Remote privilege escalation via RTP block-count overflow
Published Jun 16, 2026 · Updated Jun 16, 2026
Integer overflow in Android RTP session handling allows remote authenticated users to gain elevated privileges through crafted RTP traffic. The numberOfReportBlocks function in RtpSession.cpp permits an integer calculation to wrap, leading to an out-of-bounds write. Low-privileged network access is required; exploitation needs no user interaction and can compromise device confidentiality, integrity, and availability.
