CVE-2026-37457 1 Frrouting 1 Frrouting 2026-05-02 7.5 High
An off-by-one out-of-bounds write vulnerability in the bgp_flowspec_op_decode() function (bgpd/bgp_flowspec_util.c) of FRRouting (FRR) stable/10.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted FlowSpec component.
CVE-2026-28532 1 Frrouting 1 Frrouting 2026-05-01 6.5 Medium
FRRouting before 10.5.3 contains an integer overflow vulnerability in seven OSPF Traffic Engineering and Segment Routing TLV parser functions where a uint16_t accumulator variable truncates uint32_t values returned by the TLV_SIZE() macro, causing the loop termination condition to fail while pointer advancement continues unchecked. Attackers with an established OSPF adjacency can send a crafted LS Update packet with a malicious Type 10 or Type 11 Opaque LSA to trigger out-of-bounds memory reads and crash all affected routers in the OSPF area or autonomous system.
CVE-2026-5107 1 Frrouting 1 Frrouting 2026-04-29 4.2 Medium
A vulnerability has been found in FRRouting FRR up to 10.5.1. This affects the function process_type2_route of the file bgpd/bgp_evpn.c of the component EVPN Type-2 Route Handler. The manipulation leads to improper access controls. The attack can be initiated remotely. The attack is considered to have high complexity. The exploitability is reported as difficult. The identifier of the patch is 7676cad65114aa23adde583d91d9d29e2debd045. To fix this issue, it is recommended to deploy a patch.
CVE-2024-44070 2 Frrouting, Redhat 2 Frrouting, Enterprise Linux 2025-11-04 9.8 Critical
An issue was discovered in FRRouting (FRR) through 10.1. bgp_attr_encap in bgpd/bgp_attr.c does not check the actual remaining stream length before taking the TLV value.
CVE-2024-31949 1 Frrouting 1 Frrouting 2025-11-04 6.5 Medium
In FRRouting (FRR) through 9.1, an infinite loop can occur when receiving a MP/GR capability as a dynamic capability because malformed data results in a pointer not advancing.
CVE-2024-31948 1 Frrouting 1 Frrouting 2025-11-04 6.5 Medium
In FRRouting (FRR) through 9.1, an attacker using a malformed Prefix SID attribute in a BGP UPDATE packet can cause the bgpd daemon to crash.
CVE-2023-47235 2 Frrouting, Redhat 3 Frrouting, Enterprise Linux, Rhel Eus 2025-11-04 6.8 Medium
An issue was discovered in FRRouting FRR through 9.0.1. A crash can occur when a malformed BGP UPDATE message with an EOR is processed, because the presence of EOR does not lead to a treat-as-withdraw outcome.
CVE-2023-47234 2 Frrouting, Redhat 3 Frrouting, Enterprise Linux, Rhel Eus 2025-11-04 7.5 High
An issue was discovered in FRRouting FRR through 9.0.1. A crash can occur when processing a crafted BGP UPDATE message with a MP_UNREACH_NLRI attribute and additional NLRI data (that lacks mandatory path attributes).
CVE-2023-46753 2 Frrouting, Redhat 2 Frrouting, Enterprise Linux 2025-11-04 5.9 Medium
An issue was discovered in FRRouting FRR through 9.0.1. A crash can occur for a crafted BGP UPDATE message without mandatory attributes, e.g., one with only an unknown transit attribute.
CVE-2023-46752 2 Frrouting, Redhat 2 Frrouting, Enterprise Linux 2025-11-04 5.9 Medium
An issue was discovered in FRRouting FRR through 9.0.1. It mishandles malformed MP_REACH_NLRI data, leading to a crash.
CVE-2023-38407 2 Frrouting, Redhat 3 Frrouting, Enterprise Linux, Rhel Eus 2025-11-04 7.5 High
bgpd/bgp_label.c in FRRouting (FRR) before 8.5 attempts to read beyond the end of the stream during labeled unicast parsing.
CVE-2023-38406 2 Frrouting, Redhat 3 Frrouting, Enterprise Linux, Rhel Eus 2025-11-04 9.8 Critical
bgpd/bgp_flowspec.c in FRRouting (FRR) before 8.4.3 mishandles an nlri length of zero, aka a "flowspec overflow."
CVE-2022-37035 1 Frrouting 1 Frrouting 2025-11-04 8.1 High
An issue was discovered in bgpd in FRRouting (FRR) 8.3. In bgp_notify_send_with_data() and bgp_process_packet() in bgp_packet.c, there is a possible use-after-free due to a race condition. This could lead to Remote Code Execution or Information Disclosure by sending crafted BGP packets. User interaction is not needed for exploitation.
CVE-2022-26129 1 Frrouting 1 Frrouting 2025-11-04 7.8 High
Buffer overflow vulnerabilities exist in FRRouting through 8.1.0 due to wrong checks on the subtlv length in the functions, parse_hello_subtlv, parse_ihu_subtlv, and parse_update_subtlv in babeld/message.c.
CVE-2022-26128 1 Frrouting 1 Frrouting 2025-11-04 7.8 High
A buffer overflow vulnerability exists in FRRouting through 8.1.0 due to a wrong check on the input packet length in the babel_packet_examin function in babeld/message.c.
CVE-2022-26127 1 Frrouting 1 Frrouting 2025-11-04 7.8 High
A buffer overflow vulnerability exists in FRRouting through 8.1.0 due to missing a check on the input packet length in the babel_packet_examin function in babeld/message.c.
CVE-2022-26126 2 Fedoraproject, Frrouting 2 Fedora, Frrouting 2025-11-04 7.8 High
