What is CVE-2022-43681?

An out-of-bounds read vulnerability exists in the BGP daemon of FRRouting FRR that affects versions through 8.4. When a malformed BGP OPEN message is processed, it can cause the daemon to read beyond the allocated memory bounds. This misbehavior triggers a SIGABRT signal, leading to an unexpected exit and subsequent restart of the bgpd daemon. Consequently, this results in a Denial-of-Service (DoS) condition, which can disrupt network routing operations.
