CVE-2024-34088: Null Pointer Dereference
First published: Tue Apr 30 2024(Updated: )
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.
