Overview

CVE-2026-37228 is a high-severity vulnerability. It was published on June 1, 2026 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

FlexRIC v2.0.0 contains a reachable assertion in e2ap_recv_sctp_msg() (src/lib/ep/e2ap_ep.c). The function allocates a fixed 32KB receive buffer and enforces assert(rc < len) on the sctp_recvmsg() return value. A remote unauthenticated attacker can send a single SCTP message with payload >= 32,768 bytes to crash the near-RT RIC, iApp, E2 Agent, or xApp process via SIGABRT. No valid E2AP PDU is required. All four SCTP endpoint types (ports 36421 and 36422) share this vulnerable code path. In Release builds (NDEBUG), the stripped assertion leads to a signed-to-unsigned integer overflow and potential out-of-bounds read.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. 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.
