CVE-2026-92368Hinoki check available

Code execution via mismatched recording decompression size

Published Sep 29, 2026 · Updated Sep 29, 2026

Heap-based buffer overflow in TeamViewer Full Client and Host before 15.82 allows remote attackers to execute code via crafted .tvs files. The session-recording decompressor uses mismatched sizes for recorded data, allowing decompression to write beyond a heap buffer. Exploitation requires a user on Linux or macOS to open the file through the Play or convert recorded session feature, and execution remains within that user's privileges.
