CVE-2026-49759

CVE-2026-49759 affects Erlang OTP erts inet_drv SCTP error handling. The sctp_parse_error_chunk() writes cause codes into a fixed-size stack-allocated spec[] without bounds checks, allowing a remote attacker who has SCTP access to overflow the stack and crash the BEAM VM (DoS). A crafted SCTP ERR...

CVE-2026-49759 Stack buffer overflow in SCTP error cause parsing in inet_drv allows remote VM crash

Stack-based Buffer Overflow vulnerability in Erlang OTP erts inetdrv allows an unauthenticated remote attacker to crash the BEAM VM by sending a crafted SCTP ERROR chunk. The sctpparseerrorchunk function in erts/emulator/drivers/common/inetdrv.c parses SCTP ERROR chunks and writes cause codes int...

Erlang/OTP -- buffer overflow parsing SCTP ERROR/ABORT chunks

https://github.com/erlang/otp/security/advisories/GHSA-6f4f-chj5-5g97 reports: A buffer overflow error when parsing SCTP ERROR or ABORT chunks has been fixed. This could lead to stack corruption and VM crash, but ultimately with hard work by an attacker be refined into maybe even remote code...

Netty: SCTP reassembly nests buffers without bound

For each non-complete SctpMessage fragment the handler does fragments.putstreamId, Unpooled.wrappedBufferfrag, byteBuf, wrapping the previous accumulator and the new slice into a new CompositeByteBuf every time. After N fragments the accumulator is an N-deep chain of composites, each holding...

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-2026-37228

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-2026-37220

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...

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 stems from the assertion in the e2aprecvsctpmsg function, where assertrc len is used. This could allow unauthorized remote attackers to send SCT...

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-2026-37235

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 ...
