menglong2234 discovered NULL pointer exceptions in net-snmp, a suite of Simple Network Management Protocol applications, which could could result in denial of service.

A remote attacker (with write access) could trigger a NULL dereference while handling ipDefaultTTL via a crafted UDP packet.

CVE-2022-44793

A remote attacker (with write access) could trigger a NULL dereference while handling ipv6IpForwarding via a crafted UDP packet.
