Summary
Details

Genymobile/scrcpy versions up to and including 3.3.3, prior to commit 3e40b24, contain a buffer overflow vulnerability in the sc_device_msg_deserialize() function. A compromised device can send crafted messages that cause out-of-bounds reads, which may result in memory corruption or a denial-of-service condition. This vulnerability may allow further exploitation on the host system.
