net/mail: golang: net/mail: Denial of Service via pathological email address parsing

A flaw was found in the net/mail package within the Go standard library. A remote attacker could provide specially crafted, pathological email addresses. When these malformed email addresses are parsed by the consumePhrase function, it can lead to excessive resource consumption due to quadratic...

CVE-2026-37226

FlexRIC v2.0.0 crashes when the iApp receives an E42RICSUBSCRIPTIONREQUEST referencing a non-existent E2 Node. The lookup function returns NULL, which is enforced by assert in Debug builds SIGABRT and dereferenced in Release builds SIGSEGV. A remote unauthenticated attacker can crash the iApp...

PT-2026-45510

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...

PT-2026-45430

FlexRIC v2.0.0 crashes when an SCTP association is closed before an E2 SETUP REQUEST is sent. The near-RT RIC assumes a mapping between SCTP association and E2 node always exists in the cleanup path and enforces this via assert. A remote unauthenticated attacker can crash the near-RT RIC port 364...

CVE-2026-37226

FlexRIC v2.0.0 crashes when the iApp receives an E42RICSUBSCRIPTIONREQUEST referencing a non-existent E2 Node. The lookup function returns NULL, which is enforced by assert in Debug builds SIGABRT and dereferenced in Release builds SIGSEGV. A remote unauthenticated attacker can crash the iApp...

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-2026-37231

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-2026-37224

Summary: FlexRIC v2.0.0 crashes when it receives two identical E2_SETUP_REQUEST messages from the same or spoofed E2 Nodes. The iApp registry enforces node ID uniqueness via an assert(), not a graceful rejection, leading to a remote unauthenticated crash of the iApp process (port 36421) and a SIG...

CVE-2026-37224

FlexRIC v2.0.0 crashes when receiving a duplicate E2SETUPREQUEST from the same or spoofed E2 Node. The iApp registry enforces node ID uniqueness via assert rather than graceful rejection. A remote unauthenticated attacker can crash the iApp process port 36421 by sending two E2SETUPREQUESTs with t...

CVE-2026-37220

FlexRIC v2.0.0 crashes when an SCTP association is closed before an E2SETUPREQUEST is sent. The near-RT RIC assumes a mapping between SCTP association and E2 node always exists in the cleanup path and enforces this via assert. A remote unauthenticated attacker can crash the near-RT RIC port 36421...

PT-2026-45509

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...

Mosaic5G FlexRIC 异常处理不当漏洞

FlexRIC is an open-source RAN intelligent controller developed by Mosaic5G. The FlexRIC v2.0.0 version contains a security vulnerability. This vulnerability stems from the use of the assert function to enforce the existence of pending events when processing RICSUBSCRIPTIONRESPONSE with an unknown...

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-2026-37222

FlexRIC v2.0.0 uses hardcoded assertions to validate Information Element IE counts in decoded E2AP messages. A remote unauthenticated attacker can send a valid E2AP PDU containing an unexpected number of IEs e.g., an E2setupRequest with extra optional fields to crash the near-RT RIC port 36421 or...

CVE-2026-37226

FlexRIC v2.0.0 is vulnerable: when the iApp receives an E42_RIC_SUBSCRIPTION_REQUEST referencing a non-existent E2 Node, the lookup returns NULL and triggers an abort in Debug builds (SIGABRT) or a segfault in Release builds (SIGSEGV), allowing a remote unauthenticated attacker to crash the iApp ...

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...

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 ...
