Technical details
A mismatched memory management routine vulnerability in the routing protocol daemon (rpd) allows an authenticated network-based attacker to trigger a denial of service by sending a malformed BGP route update when extended next-hop tunneling and SRv6 service processing are both enabled. The vulnerability results in a crash of the rpd process. An attacker must be authenticated on the BGP session and have network reachability to send the malicious update.
