DescriptionCVE.org

UERANSIM before 3.2.6 allows out-of-bounds read when a RLS packet is sent to gNodeB with malformed PDU length. This occurs in function readOctetString in src/utils/octet_view.cpp and in function DecodeRlsMessage in src/lib/rls/rls_pdu.cpp

AnalysisAI

UERANSIM before 3.2.6 allows out-of-bounds read when a RLS packet is sent to gNodeB with malformed PDU length. Rated medium severity (CVSS 5.5), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.

Technical ContextAI

This vulnerability is classified as Out-of-bounds Read (CWE-125), which allows attackers to read data from memory outside the intended buffer boundaries.
