CVE-2026-37235

FlexRIC v2.0.0 trusts the xappid field from E42 message payloads without binding it to the sender's SCTP association. The validation function validxappid only checks that the value is within the assigned range. A remote unauthenticated attacker can impersonate any xApp by specifying their xappid ...

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...

PT-2026-45512

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

Name of the Vulnerable Software and Affected Versions FlexRIC version 2.0.0 Description A flaw allows a single SCTP connection to bind multiple xapp ids by sending multiple E42 SETUP REQUESTs. Upon disconnection, the system only cleans up resources for the first registered xapp id, leaving...

CVE-2026-37235

FlexRIC v2.0.0 trusts the xapp_id field from E42 payloads without binding it to the sender’s SCTP association. The valid_xapp_id() check only ensures the value is within the assigned range, enabling a remote unauthenticated attacker to impersonate any xApp by supplying their xapp_id in requests t...

OpenAirInterface5G 2.4.0 (nr-softmodem) E2SM-KPM RAN Function PRB utilization calculation (fill_RRU_PrbTotDl/Ul in openair2/E2AP/RAN_FUNCTION/O-RAN/ran_func_kpm_subs.c) divides PRB difference by the previous total_prb_aggregate, missing a zero-check. If two consecutive samples are identical and a...

CVE-2026-37234

CVE-2026-37234 affects FlexRIC v2.0.0. A single SCTP connection can bind multiple xapp_ids via multiple E42_SETUP_REQUESTs. Upon disconnect, only the first registered xapp_id’s resources are cleaned up; other xapp_ids and their subscriptions remain as stale entries, allowing a remote attacker to ...
