Mongoose is an embedded web server and network library. Prior to 7.23, the built-in TLS stack selected by MG_TLS_BUILTIN in src/tls_builtin.c accepts a TLS 1.3 record whose decrypted size is exactly the 16-byte authentication tag with no plaintext or ContentType byte. In mg_tls_recv_record(), the msgsz length check permits that record and the recv_len calculation underflows to SIZE_MAX, so a later handshake step treats stale buffer contents as a trusted message with an effectively unbounded length. An unauthenticated malicious TLS peer can trigger a heap out-of-bounds read before certificate or Finished validation, causing a remote denial of service. This issue is fixed in version 7.23.

CVE-2026-1108102.8 LOW—
——0A vulnerability was detected in ggml-org whisper.cpp up to 1.9.4. This affects the function whisper_model_load of the file src/whisper.cpp of the component Model Loader. Performing a manipulation of the argument ttype results in out-of-bounds read. The attack must be initiated from a local position. The exploit is now public and may be used. Upgrading to version 1.9.5 is able to mitigate this issue. The patch is named 60c0be6ac8fa71b1a2ae2dd938a31a34a508e774. It is recommended to upgrade the affected component. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.6hCVE-2026-1106946.3 MED—
——0A vulnerability has been found in OAID Tengine up to 1.12.0. This vulnerability affects the function get_tm_file_model of the file source/serializer/tmfile/tm2_serializer.c of the component tmfile Model Loader. Such manipulation of the argument offset_root leads to out-of-bounds read. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The project was informed of the problem early through an issue report but has not responded yet.10hCVE-2026-1106797.3 HIG—
——0A vulnerability was determined in OpenSIPS up to 3.6.8/4.0.1. The impacted element is the function rtpproxy_offer/rtpproxy_answer of the component rtpproxy. This manipulation causes out-of-bounds read. The attack may be initiated remotely. Upgrading to version 3.6.9 and 4.0.2 is sufficient to resolve this issue. It is advisable to upgrade the affected component.10hCVE-2026-732617.5 HIG—
——0Mongoose is an embedded web server and network library. Prior to 7.23, the built-in TCP/IP stack enabled by MG_ENABLE_TCPIP in src/net_builtin.c does not reject a TCP option whose declared opts[1] length exceeds the remaining option bytes. In handle_opt(), a NOP followed by a truncated MSS option causes opts[3] to be read outside the declared options area and used as the low byte of dmss. An unauthenticated remote peer can corrupt the per-connection MSS value so later mg_send() calls transmit truncated or zero-length application payloads while the TCP connection otherwise appears healthy. This issue is fixed in version 7.23.12hCVE-2026-732607.5 HIG—
——0Mongoose is an embedded web server and network library. Prior to 7.23, the built-in TLS certificate parser selected by MG_TLS_BUILTIN fails to verify that a long-form DER element length fits within the remaining certificate buffer. In mg_der_to_tlv() and mg_der_next(), a peer-controlled length can advance the parser beyond the certificate and underflow the remaining uint32_t length, causing mg_tls_parse_cert_der() to continue walking an invalid pointer. An unauthenticated malicious TLS server, or a client presenting a certificate to a server configured for client certificates, can trigger an out-of-bounds read and denial of service during the handshake. This issue is fixed in version 7.23.12hCVE-2026-636268.8 HIG—
——0Mongoose is an embedded web server and network library. Prior to 7.23, ppp_handle_ipv6cp() in src/l2_ppp.c trusts the 16-bit IPv6CP len field without checking it against the received payload size. On a PPP or PPPoE link using MG_ENABLE_TCPIP and MG_ENABLE_IPV6, an unauthenticated adjacent peer can complete the required LCP exchange and send a short Configure-Request with an oversized length, causing ppp_tx_frame() to read beyond recv_queue.buf and write beyond tx.buf. The same length misuse can also expose adjacent heap bytes in a reply or hang the event loop through find_opt(). This issue is fixed in version 7.23.12h
