pyasn1: pyasn1 Vulnerable to Denial of Service via Unbounded Recursion

An unbounded recursion flaw has been discovered in the pypi pyasn1 library. This uncontrolled recursion occurs when decoding ASN.1 data with deeply nested structures. An attacker can supply a crafted payload containing nested SEQUENCE 0x30 or SET 0x31 tags with Indefinite Length 0x80 markers. Thi...

CVE-2026-37229

CVE-2026-37229 affects FlexRIC v2.0.0. A reachable assertion in e2ap_create_pdu() is triggered when ASN.1 PER decoding fails, allowing a remote unauthenticated attacker to send a non-PER byte sequence (e.g., 0x00) over SCTP to the near-RT RIC at port 36421 or iApp at port 36422 to crash the proce...
