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...

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...

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...

FlexRIC v2.0.0 uses a uint16 t counter for xapp id assignment but stores the value in uint32 t message fields. After 65,530+ E42 SETUP REQUESTs, the 16-bit counter wraps around and produces duplicate xapp ids. The iApp port 36422 crashes when attempting to register a duplicate ID in its internal...

CVE-2026-37232

A divide-by-zero vulnerability exists in OpenAirInterface5G version 2.4.0 within the nr-softmodem component's E2SM-KPM RAN Function. Specifically, the functions fill_RRU_PrbTotDl() and fill_RRU_PrbTotUl() in openair2/E2AP/RAN_FUNCTION/O-RAN/ran_func_kpm_subs.c (lines 182 and 197) calculate PRB us...
