6.5CVE-2022-43681debianfrr+3
EPSS score
2.13%
An out-of-bounds read exists in the BGP daemon of FRRouting FRR through 8.4. When sending a malformed BGP OPEN message that ends with the option length octet (or the option length word, in case of an extended OPEN message), the FRR code reads of out of the bounds of the packet, throwing a SIGABRT signal and exiting. This results in a bgpd daemon restart, causing a Denial-of-Service condition.

bgpd in FRRouting (FRR) before 2.0.2 and 3.x before 3.0.2, as used in Cumulus Linux before 3.4.3 and other products, allows remote attackers to obtain sensitive information via a malformed BGP UPDATE packet from a connected peer, which triggers transmission of up to a few thousand unintended bytes because of a mishandled attribute length, aka RN-690 (CM-18492).
6.5CVE-2024-31950debianfrr+2
EPSS score
0.51%
In FRRouting (FRR) through 9.1, there can be a buffer overflow and daemon crash in ospf_te_parse_ri for OSPF LSA packets during an attempt to read Segment Routing subTLVs (their size is not validated).
6.5CVE-2024-31949debianfrr+2
EPSS score
0.70%
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.
6.5CVE-2024-31948debianfrr+13
EPSS score
0.83%
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.
6.5CVE-2024-31951debianfrr+2
EPSS score
0.55%
In the Opaque LSA Extended Link parser in FRRouting (FRR) through 9.1, there can be a buffer overflow and daemon crash in ospf_te_parse_ext_link for OSPF LSA packets during an attempt to read Segment Routing Adjacency SID subTLVs (lengths are not validated).
6.5CVE-2024-27913debianfrr+3
EPSS score
0.32%
ospf_te_parse_te in ospfd/ospf_te.c in FRRouting (FRR) through 9.1 allows remote attackers to cause a denial of service (ospfd daemon crash) via a malformed OSPF LSA packet, because of an attempted access to a missing attribute field.
9.8CVE-2024-44070debianfrr+19
EPSS score
0.64%
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.
7.5CVE-2024-34088debianfrr+2
EPSS score
0.69%
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.
6.5CVE-2019-5892frroutingfrrouting
EPSS score
2.72%
bgpd in FRRouting FRR (aka Free Range Routing) 2.x and 3.x before 3.0.4, 4.x before 4.0.1, 5.x before 5.0.2, and 6.x before 6.0.2 (not affecting Cumulus Linux or VyOS), when ENABLE_BGP_VNC is used for Virtual Network Control, allows remote attackers to cause a denial of service (peering session flap) via attribute 255 in a BGP UPDATE packet. This occurred during Disco in January 2019 because FRR does not implement RFC 7606, and therefore the packets with 255 were considered invalid VNC data and the BGP session was closed.
7.5CVE-2026-37457debianfrr+7
EPSS score
0.72%
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.
6.5CVE-2026-37458debianfrr+4
EPSS score
0.44%
Missing input validation in the MP_REACH_NLRI component of FRRouting (FRR) stable/10.0 to stable/10.6 allows authenticated attackers to cause a Denial of Service (DoS) via supplying a crafted UPDATE message.
4.2CVE-2026-5107debianfrr+5
EPSS score
0.37%
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.
6.5CVE-2026-28532debianfrr+4
EPSS score
0.37%
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.
7.5CVE-2023-41909debianfrr+5
EPSS score
1.12%
An issue was discovered in FRRouting FRR through 9.0. bgp_nlri_parse_flowspec in bgpd/bgp_flowspec.c processes malformed requests with no attributes, leading to a NULL pointer dereference.
7.5CVE-2023-41358debianfrr+5
EPSS score
1.25%
An issue was discovered in FRRouting FRR through 9.0. bgpd/bgp_packet.c processes NLRIs if the attribute length is zero.
9.1CVE-2023-41360debianfrr+5
EPSS score
1.15%
An issue was discovered in FRRouting FRR through 9.0. bgpd/bgp_packet.c can read the initial byte of the ORF header in an ahead-of-stream situation.
9.1CVE-2023-41359fedoraprojectfedora+1
EPSS score
1.15%
An issue was discovered in FRRouting FRR through 9.0. There is an out-of-bounds read in bgp_attr_aigp_valid in bgpd/bgp_attr.c because there is no check for the availability of two bytes during AIGP validation.
9.8CVE-2023-41361debianfrr+2
EPSS score
0.90%
An issue was discovered in FRRouting FRR 9.0. bgpd/bgp_open.c does not check for an overly large length of the rcv software version.
7.5CVE-2023-47235debianfrr+2
EPSS score
0.69%
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.
