CVE-2026-37229: n/a
FlexRIC v2. 0. 0 has a vulnerability in the e2ap_create_pdu() function where an assertion failure occurs if ASN. 1 PER decoding fails. A remote unauthenticated attacker can send malformed non-PER byte sequences over SCTP to specific ports, causing the process to crash via SIGABRT. This affects all three E2AP protocol versions (v1. 01, v2. 03, v3. 01). No patch or official remediation guidance is currently available.
AI Analysis
Technical Summary
The vulnerability in FlexRIC v2.0.0 involves a reachable assertion triggered in the e2ap_create_pdu() function when ASN.1 PER decoding fails. An attacker can exploit this by sending any non-PER encoded byte sequence (e.g., a single 0x00 byte) over SCTP to the near-RT RIC (port 36421) or iApp (port 36422). This causes the process to abort with a SIGABRT signal before any protocol-level validation is performed. All supported E2AP protocol versions are affected. The vulnerability allows remote denial of service via process crash but does not require authentication.
Potential Impact
A remote unauthenticated attacker can cause a denial of service by crashing the FlexRIC process through sending malformed SCTP packets. This results in service disruption of the near-RT RIC or iApp components. There is no indication of code execution or data compromise from the provided data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider restricting access to the affected SCTP ports (36421 and 36422) to trusted sources to reduce exposure.
