CVE-2026-37229

FlexRIC v2.0.0 contains a reachable assertion in e2apcreatepdu triggered when ASN.1 PER decoding fails. A remote unauthenticated attacker can send any non-PER byte sequence e.g., a single 0x00 byte over SCTP to the near-RT RIC port 36421 or iApp port 36422 to crash the process via SIGABRT. The...

CVE-2026-37231

FlexRIC v2.0.0 uses a uint16t counter for xappid assignment but stores the value in uint32t message fields. After 65,530+ E42SETUPREQUESTs, the 16-bit counter wraps around and produces duplicate xappids. The iApp port 36422 crashes when attempting to register a duplicate ID in its internal data...

CVE-2026-37222

FlexRIC v2.0.0 contains a vulnerability where the stack asserts exact Information Element (IE) counts in decoded E2AP messages instead of validating against protocol ranges. An unauthenticated remote attacker can send a valid E2AP PDU (for example, an E2setupRequest with extra optional fields) th...

CVE-2026-37221

FlexRIC v2.0.0 is affected. Processing a RIC_SUBSCRIPTION_RESPONSE with an unknown ric_id that has no corresponding pending event can trigger an assertion failure (near-RT RIC) leading to SIGABRT in Debug builds or a NULL pointer dereference (SIGSEGV) in Release builds. This can be exploited remo...

CVE-2026-37228

FlexRIC v2.0.0 contains a reachable assertion in e2aprecvsctpmsg src/lib/ep/e2apep.c. The function allocates a fixed 32KB receive buffer and enforces assertrc = 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 endpoin...

CVE-2026-37234

FlexRIC v2.0.0 allows a single SCTP connection to bind multiple xappids by sending multiple E42SETUPREQUESTs. On disconnect, only the first registered xappid's resources are cleaned up; subsequent xappids and their subscriptions remain as stale entries. A remote attacker can exploit this to leak...

CVE-2026-37233

FlexRIC v2.0.0 contains an authorization bypass in the iApp's xApp isolation mechanism. The equality function eqxappricgenid in src/ric/iApp/xappricid.c compares m0-xappid against itself m0-xappid instead of the other argument m1-xappid, effectively ignoring the xApp identity dimension. A malicio...

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 assertrc = 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...

CVE-2026-37230

FlexRIC v2.0.0 crashes when the near-RT RIC receives a RICINDICATION message with a ranfuncid that does not exist in its registry. The lookup returns NULL, triggering assert in Debug builds SIGABRT or NULL pointer dereference in Release builds SIGSEGV. A remote unauthenticated attacker can crash...

CVE-2026-37231

FlexRIC v2.0.0 contains a bug where a uint16_t counter used for xapp_id assignment is stored in uint32_t message fields. After 65,530+ E42_SETUP_REQUESTs, the 16-bit counter wraps, causing duplicate xapp_ids. The iApp on port 36422 crashes when it attempts to register a duplicate ID within its in...

FlexRIC 安全漏洞

FlexRIC is an open-source RAN intelligent controller developed by Mosaic5G. The FlexRIC v2.0.0 version contains a security vulnerability. This vulnerability arises from the use of a uint16t counter for xappid assignment, but the counter is stored in a uint32t field. As a result of this counter...

FlexRIC 安全漏洞

FlexRIC is an open-source RAN intelligent controller developed by Mosaic5G. Version FlexRIC v2.0.0 contains a security vulnerability. This vulnerability arises from handling RICINDICATION messages that do not contain the ranfuncid field, causing an assert to be triggered or null pointer...

FlexRIC 安全漏洞

FlexRIC is an open-source RAN intelligent controller developed by Mosaic5G. Version FlexRIC v2.0.0 contains a security vulnerability. This vulnerability arises from the fact that when the lookup function returns NULL, the assert function during debugging builds triggers a SIGABRT, or in release...

Mosaic5G FlexRIC 异常处理不当漏洞

FlexRIC is an open-source RAN intelligent controller developed by Mosaic5G. Version FlexRIC v2.0.0 contains a security vulnerability. This vulnerability arises from the use of hardcoded assertions to verify the count of information elements in E2AP messages, rather than using the protocol-specifi...

FlexRIC v2.0.0 crashes when the near-RT RIC receives a RIC INDICATION message with a ran func id that does not exist in its registry. The lookup returns NULL, triggering assert in Debug builds SIGABRT or NULL pointer dereference in Release builds SIGSEGV. A remote unauthenticated attacker can cra...

CVE-2026-37220

FlexRIC v2.0.0 crashes when an SCTP association is closed before an E2_SETUP_REQUEST is sent. The near-RT RIC assumes a persistent SCTP↔E2 node mapping in the cleanup path and enforces this with an assert(), enabling a remote unauthenticated attacker to crash the near-RT RIC (port 36421) by compl...
