6.5 · MEDIUMOverview
CVE-2026-28532 is a medium-severity vulnerability affecting frrouting frrouting. It was published on April 30, 2026 and has a CVSS 3.1 base score of 6.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 6.5, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from frrouting. Update frrouting to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
