CVE-2022-40302 is a denial-of-service vulnerability affecting FRRouting (FRR) through version 8.4, specifically within its bgpd component. Attackers can trigger an assertion failure or out-of-bounds read by sending a specially crafted BGP OPEN message with an Extended Length option, exploiting inconsistent boundary checks. This medium-severity vulnerability (CVSS 6.5) requires low privileges and network access, leading to high availability impact. There is no evidence of active exploitation, public exploit code, or significant community discussion, though it has received some media coverage.
