Root code execution via SMB2 use-after-free
Published Jun 6, 2024 · Updated Aug 1, 2024
Use-after-free in Sonos Era 100 15.9 allows network-adjacent attackers to execute arbitrary code through crafted SMB2 messages. The SMB2 handler operates on an object without first confirming that it still exists, allowing reuse of freed memory. No authentication is required, and successful exploitation runs code as root on the speaker.
