CVE-2026-102721 (GCVE-0-2026-102721)

Title
TFTP client and server copy the ERROR packet message without bounding the read against the packet
Summary
In Eclipse ThreadX NetX Duo versions 6.0 through 6.5.2.202603a, the TFTP client copies the message of a received ERROR packet without bounding the copy by the end of the datagram, and the TFTP server reads one byte past a minimal ERROR packet. A malicious TFTP server can make the client copy up to 64 bytes of adjacent packet-pool memory into the error string the application retrieves, or fault on targets with memory protection.

CVE-2026-102720 (GCVE-0-2026-102720)

Title
DHCP client option walk drifts one byte per skipped option, reading past the received message and past the saved options buffer
Summary
In Eclipse ThreadX NetX Duo versions 6.0 through 6.5.2.202603a, the DHCP client's option walk advances its offset one byte less than its read pointer for every option it skips. A DHCP server, or any host on the link that answers first, can make the client read up to about a kilobyte past the received message, and the same walk copies out-of-bounds bytes into the application's buffer when it retrieves a user option.

CVE-2026-102718 (GCVE-0-2026-102718)

Vulnerability from cvelistv5 – Published: 2026-09-29 17:44 – Updated: 2026-11-04 13:18

Title
Out-of-bounds read in the NetX Duo SNMP OID parser via a multi-byte BER length
Summary
In Eclipse ThreadX NetX Duo versions up to and including 6.5.2.202603, the SNMP agent's OID parser uses a multi-byte BER length from the request without checking it against the bytes present, and reads past the end of the packet buffer. A remote, unauthenticated attacker can send a crafted SNMP request that makes the agent read adjacent memory into its OID state, faulting the agent on targets with memory protection.

CVE-2026-102714 (GCVE-0-2026-102714)

Vulnerability from cvelistv5 – Published: 2026-09-29 17:41 – Updated: 2026-11-04 13:06
VLAI
Title
ICMPv6 option validation accepts a trailing byte residue, sending the Router Advertisement, Neighbor Solicitation, Neighbor Advertisement and Redirect option walkers past the packet or into a permanent loop
Summary
In Eclipse ThreadX NetX Duo versions up to and including 6.5.2.202603, built with IPv6, the ICMPv6 option validator accepts an option area that ends in a one- or two-byte residue, and the Router Advertisement, Neighbor Solicitation, Neighbor Advertisement and Redirect handlers then walk it without length checks. A host on the local link can send one such message to make the IP thread read past the packet or loop forever, and can place off-packet memory in the neighbor cache.

CVE-2026-102713 (GCVE-0-2026-102713)

Vulnerability from cvelistv5 – Published: 2026-09-29 17:40 – Updated: 2026-11-04 13:03

Title
Unbounded DATA datagram in the NetX Duo TFTP server causes an out-of-bounds read and a permanent stall
Summary
In Eclipse ThreadX NetX Duo versions up to and including 6.5.2.202603, built with packet chaining, the TFTP server does not bound the length of a received DATA datagram. An unauthenticated peer can upload an oversized datagram that writes memory beyond the received packet into the file and read it back by downloading the file, and the same datagram can suspend the server thread permanently.

CVE-2026-102712 (GCVE-0-2026-102712)

Title
Out-of-bounds read in the NetX Secure DTLS ClientHello parser
Summary
In Eclipse ThreadX NetX Duo versions up to and including 6.5.2.202603, built with DTLS server support, the NetX Secure DTLS server's ClientHello parser reads the session ID, cookie and ciphersuite list without bounding them by the bytes remaining in the message. An unauthenticated peer can send a ClientHello declaring fields longer than the message and make the server read past it; nothing read is sent back to the peer, and the read can fault the server only on targets that trap the address beyond the buffer.

CVE-2026-102711 (GCVE-0-2026-102711)

Vulnerability from cvelistv5 – Published: 2026-09-29 17:38 – Updated: 2026-11-04 09:29

Title
Out-of-bounds Read and Unverified Entry Pointers in the ThreadX Module Loader
Summary
In Eclipse ThreadX versions 6.0.1 through 6.5.2.202603, the Module Manager loaders take a module image without its length and trust the sizes and offsets in its preamble. A crafted module image can declare a code size larger than the image to read, or gain access to, the memory that follows it, and can place its entry points outside its code.
Severity

Title
CTranslate2 before 4.8.1 Out-of-Bounds Read via Model Deserialization
Summary
CTranslate2 before 4.8.1 contains an out-of-bounds heap read vulnerability in the binary model loader when deserializing string fields without null terminators. Attackers can craft malicious model files to trigger heap memory reads past buffer boundaries, causing crashes or disclosing adjacent heap memory contents.

CVE-2026-102560 (GCVE-0-2026-102560)

Title
Libsoup: libsoup: heap buffer overflow during outgoing permessage-deflate buffer growth
Summary
A flaw was found in libsoup. When the permessage-deflate WebSocket extension compresses a very large outgoing message, truncated size calculations used for GByteArray growth could wrap, causing zlib to write past the allocated buffer and resulting in a heap buffer overflow.
Severity
8.6 (High)

Implementation

Strategy: Input Validation

  • Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
  • When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
  • Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
  • To reduce the likelihood of introducing an out-of-bounds read, ensure that you validate and ensure correct calculations for any length argument, buffer size calculation, or offset. Be especially careful of relying on a sentinel (i.e. special character such as NUL) in untrusted inputs.
Mitigation
Architecture and Design

Strategy: Language Selection

Use a language that provides appropriate memory abstractions.

CAPEC-540: Overread Buffers

An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.
