CVE-2024-34088 (GCVE-0-2024-34088)

Vulnerability from cvelistv5 – Published: 2024-04-30 00:00 – Updated: 2024-11-20 16:34
VLAI
Summary
In FRRouting (FRR) through 9.1, it is possible for the get_edge() function in ospf_te.c in the OSPF daemon to return a NULL pointer. In cases where calling functions do not handle the returned NULL value, the OSPF daemon crashes, leading to denial of service.
