| Issue summary: The DTLS retransmission logic does not correctly handle a handshake message write that is suspended part-way through. The retransmitted message can be read past the message buffer and the retransmission overwrites the internal state the suspended write needs to resume correctly. Impact summary: The retransmitted message can disclose a heap memory to the peer as plaintext handshake data or cause a crash and a Denial of Service when the read reaches an unmapped memory region. CWE: CWE-125: Out-of-bounds Read Description: DTLS handshake messages can be written out in multiple fragments, and a write can suspend mid-message (returning WANT_WRITE) if the underlying transport temporarily cannot accept more data. While such a write is suspended, the DTLS retransmission timer may independently fire and ask the retransmission logic to resend an earlier, already-acknowledged-as-sent message from its retransmit queue. The retransmission logic reused the same internal buffer and position tracking as the message that was still being written, without resetting the position back to the start of the message being retransmitted. As a result the retransmission was read starting from wherever the suspended write had left off, producing a mislabelled message whose body was leftover bytes from the other, larger message still in flight - content that was never meant to be sent at that point, and which could run past the end of the allocated buffer. Separately, even when the retransmission is positioned correctly, allowing it to run to completion while another write is suspended overwrites the same shared bookkeeping that the suspended write depends on to resume. When the application later resumes the suspended write (via a subsequent SSL_read(), SSL_write(), SSL_accept(), or SSL_connect() call), it finds that bookkeeping in a state inconsistent with the message and aborts the process in a debugging build. The fix resets the retransmission's read position to the start of the message before resending, and skips retransmission entirely whenever a handshake write is still suspended, deferring to the next call that resumes it instead. FIPS impact: no The affected code is outside the FIPS module boundary. | ||||
| CVE-2026-102713 | 2026-09-29 | N/A | ||
| The TFTP server accepts a DATA datagram of any size. The dispatcher rejects datagrams shorter than four bytes (nxd_tftp_server.c:1037) and nothing anywhere checks an upper bound, in particular not against the protocol maximum of 4 + NX_TFTP_FILE_TRANSFER_MAX. Two things follow from that one missing check, both reachable before any authentication because TFTP has none. The handler passes `nx_packet_length - 4` straight to FileX: ```c /* addons/tftp/nxd_tftp_server.c:1863, 1889 */ status = nx_packet_copy(packet_ptr, &temp_ptr, server_ptr -> nx_tftp_server_packet_pool_ptr, NX_WAIT_FOREVER); ... fx_file_write(&(client_request_ptr -> nx_tftp_client_request_file), packet_ptr -> nx_packet_prepend_ptr + 4, packet_ptr -> nx_packet_length - 4); ``` `nx_packet_length` is the length of a chain, not of one contiguous buffer, so FileX copies past the end of the first packet: ``` ERROR: AddressSanitizer: heap-buffer-overflow READ of size 1280 at 0x621000001108 thread T5 #0 __interceptor_memcpy #1 _fx_utility_memory_copy filex/common/src/fx_utility_memory_copy.c:78 0x621000001108 is 0 bytes to the right of 4104-byte region ``` Those bytes are written into the file the attacker is uploading, and a TFTP read request hands them back, so this is a memory disclosure with a convenient retrieval channel. The same datagram also wedges the server. `nx_packet_copy` at :1863 needs ceil(nx_packet_length / pool_payload) packets and asks for them with NX_WAIT_FOREVER, so when the attacker sizes the datagram beyond what the pool holds, the server thread suspends and never returns. A liveness probe after one such datagram times out with the pool at 0 of 12 packets and the server thread suspended, and no later client is served. Reject `nx_packet_length > 4 + NX_TFTP_FILE_TRANSFER_MAX` in the DATA branch before either call, and use a bounded wait rather than NX_WAIT_FOREVER for the copy. | ||||
| CVE-2026-102718 | 2026-09-29 | N/A | ||
| hey, `_nx_snmp_utility_object_id_get` in the NetX Duo SNMP addon does not validate the claimed OID data length against the actual buffer size when the OID uses BER multibyte length encoding, so a remote attacker can send a crafted SNMP packet with a multibyte OID length larger than the available buffer, causing the parser to read past the packet buffer boundary into adjacent heap memory. the OOB bytes are decoded as OID component values and written into the agents internal OID string buffer, corrupting agent state. on systems with memory protection the OOB read poses the risk of crashing the SNMP agent thread, causing denial of service. on bare metal embedded systems without memory protection the read silently succeeds and corrupts the agents internal state with heap data. | ||||

| CVE-2026-102728 | 2026-09-29 | N/A | ||
| Two client-side TLS/DTLS handshake parsers in NetX Secure read fields from a server-supplied message before validating that the message is long enough to contain them. Both are bounded out-of-bounds reads on a remotely reachable path, both are reached from a TLS or DTLS client connecting to a malicious or malformed server, and both have the same shape: the bounds check exists and returns the correct status, but it runs after the read it is meant to guard. | ||||
| CVE-2026-102820 | 2026-09-29 | 6.2 Medium | ||
| pageant provides a [PageantStream] type that implements [AsyncRead] and [AsyncWrite] traits and can be used to talk to a running Pageant instance. Prior to pageant 0.2.3, the Windows pageant crate's pageant/src/wmmessage.rs MemoryMap::read function trusts a peer-controlled u32 response length supplied through the 8192-byte Pageant shared-memory mapping reached by AgentClient::connect_pageant. A local process that impersonates the Pageant window can make query_pageant_direct allocate up to approximately 4 GiB and copy beyond the mapped view, reliably crashing a russh client and conditionally exposing adjacent committed memory. This issue is fixed in pageant 0.2.3. | ||||

| CVE-2026-102721 | 2026-09-29 | N/A | ||
| A TFTP server that answers with a short ERROR packet makes the client read up to 64 bytes past the received datagram. Each receive path checks only that the datagram is at least four bytes long (nxd_tftp_client.c:1229, 1521, 1984). When the opcode is NX_TFTP_CODE_ERROR the message string is copied with a loop whose only limits are the destination buffer and a NUL byte: ```c /* addons/tftp/nxd_tftp_client.c:1769 */ for (i = 0; (i < (sizeof(tftp_client_ptr -> nx_tftp_client_error_string) - 1)) && (*buffer_ptr); i++) ``` Nothing compares `buffer_ptr` against `nx_packet_append_ptr`. An ERROR packet that carries no terminating NUL, which a server controls completely, walks the loop off the end of the packet until it happens to meet a zero byte or fills the 64 byte destination. ``` ERROR: AddressSanitizer: heap-buffer-overflow READ of size 1 at 0x60d0000000c8 thread T4 #0 _nxd_tftp_client_file_read addons/tftp/nxd_tftp_client.c:1769 0x60d0000000c8 is 0 bytes to the right of 136-byte region ``` The open path has the same loop at :1327 and reports the same way. What is read lands in `nx_tftp_client_error_string`, which the application is expected to display or log, so adjacent packet pool memory ends up in whatever the device does with the error text. Add `(buffer_ptr < packet_ptr -> nx_packet_append_ptr)` to the loop condition in all three paths. | ||||

| CVE-2026-102730 | 2026-09-29 | N/A | ||
| Mounting an attacker-controlled NAND flash image (`lx_nand_flash_open()`) triggers an unbounded out-of-bounds heap **write** in LevelX's NAND flash-translation-layer metadata parser that overwrites a driver function pointer in the control block, giving a demonstrated control-flow hijack — RIP set to a full 8-byte attacker-chosen value (register-verified). Two accompanying OOB reads. All reproduced verbatim under ASan at HEAD `9f1cfdc`. (The affected metadata-parser header states "Some portions generated by Copilot (Sonnet 4.6)" — an AI-generated parser with an unchecked on-flash count.) | ||||

| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btintel: bound firmware ID by TLV length The firmware ID is treated as a NUL-terminated string even though the TLV length is its only boundary. If the value does not contain a NUL terminator, snprintf() can read beyond the received response. Limit the conversion to the advertised TLV value length. | ||||
