FRRouting’s OSPF implementation contains a remotely triggerable NULL-pointer dereference in the show_vty_link_info path of ospf_ext.c that can crash the ospfd process and produce a network-impacting Denial of Service (DoS) when a specially crafted OSPF packet is processed—an issue tracked as...

A remotely triggerable NULL pointer dereference in FRRouting’s OSPF implementation has been cataloged as CVE-2025-61099 and can crash the OSPF daemon (ospfd) when a crafted Link-State (LS) Update packet is processed while detailed OSPF packet debugging is enabled. The bug, present in upstream...

FRRouting's OSPF implementation contains a NULL-pointer dereference that can be triggered by a crafted OSPF packet, allowing remote attackers to crash the OSPF daemon (ospfd) and cause a Denial of Service (DoS) for routers and appliances using vulnerable FRR releases. Background FRRouting (FRR)...

A newly assigned CVE, CVE-2025-61101, identifies a NULL-pointer dereference in the FRRouting (FRR) OSPF code that can be triggered by a crafted OSPF packet and may crash the ospfd process, producing a network-impacting Denial of Service (DoS) for affected routing hosts and appliances. Background...

FRRouting has been disclosed with a cluster of NULL-pointer dereference flaws that allow a remote attacker to crash the OSPF daemon (ospfd) by sending crafted OSPF packets; the most prominent of these is tracked as CVE-2025-61102 and affects FRRouting (frr) releases from v4.0 through v10.4.1...

FRRouting has a newly documented vulnerability — tracked as CVE-2025-61100 — that allows specially crafted OSPF Link State Advertisements (LSAs) to trigger a NULL pointer dereference in the OSPF daemon (ospfd), causing a denial-of-service (DoS) condition for affected FRR installations. The fault...

FRRouting has been flagged for a serious Denial-of-Service hole: a NULL pointer dereference in OSPF packet handling (CVE-2025-61107) that can crash the ospfd daemon when a crafted LSA Update containing an opaque LSA is processed, and the problem was patched upstream via a targeted set of checks...

FRRouting has a serious denial-of-service bug — tracked as CVE-2025-61103 — that allows a crafted OSPF packet to crash the ospfd process via a NULL pointer dereference in ospf_ext.c, and operators should treat any running FRR instances that have OSPF debugging enabled as high-priority for...
