CVE-2024-2615Public exploitNetwork attack vector

Code execution via browser memory corruption

Published Mar 19, 2024 · Updated Mar 14, 2025

Memory corruption in Mozilla Firefox before 124 allows remote attackers to execute arbitrary code through malicious web content. TitleChangeEvent::Run dereferences a freed Document, while DeviceInfoPipeWire::CreateCapabilityMap copies a device ID using the display-name length. DOM activity reaches the title-event defect, while the PipeWire camera path is disabled by default; successful corruption executes code in the browser process.
