CVE-2026-73257: Inconsistent Interpretation of HTTP Requests

Mongoose is an embedded web server and network library. Priro to version 7.22, a remote unauthenticated attacker can send an HTTP request containing both Content-Length and Transfer-Encoding: chunked. The clcount and tecount checks in the mghttpparse and httpcb paths in src/http.c accept both...

PT-2026-80297

Summary io.netty.incubator:netty-incubator-codec-bhttp uses attacker-controlled Binary HTTP variable-length integers as long values but accumulates them into int offsets. Large valid varint lengths wrap the internal offset negative, leading to unchecked ArrayIndexOutOfBoundsException /...

CVE-2026-74458

A flaw was found in the Kvaser USB CAN driver kvaserusbleaf in the Linux kernel. This vulnerability occurs due to insufficient validation of received command lengths from a USB buffer. A malicious or malformed command shorter than the expected header length, or one that exceeds the destination...

CVE-2026-74460

A flaw was found in the Linux kernel's emsusb module. This vulnerability occurs because the emsusbreadbulkcallback function, which processes Controller Area Network CAN Protocol Converter CPC messages from a USB receive buffer, does not properly validate the lengths of these messages. An attacker...

CVE-2026-74532

A flaw was found in the Bluetooth btintel driver of the Linux kernel. The btinteldiagnostics function fails to validate the length of a diagnostics Vendor Specific Event VSE before accessing its data. This oversight allows an attacker to potentially read data beyond the intended memory boundary,...

USN-8650-1: Cap'n Proto vulnerabilities

Chanho Kim and Jihyeok Han discovered that Cap'n Proto incorrectly handled negative Content-Length values or excessively large chunk sizes when processing HTTP messages. An attacker could possibly use these issues to cause HTTP messages to be interpreted inconsistently, resulting in HTTP request ...

USN-8650-1 capnproto vulnerabilities

Chanho Kim and Jihyeok Han discovered that Cap'n Proto incorrectly handled negative Content-Length values or excessively large chunk sizes when processing HTTP messages. An attacker could possibly use these issues to cause HTTP messages to be interpreted inconsistently, resulting in HTTP request ...

CVE-2026-65610

nnn stores homelen variable as uchart, which can only represent values in the range 0-255. An attacker who can influence the victim's execution environment can provide an arbitrary HOME path with length that is truncated to 0. The expression homelen - 1 is promoted to signed int and becomes -1 an...

EUVD-2026-62398

nnn is vulnerable to Out-of-Bound write vulnerability. Due to lack of validation of attacker-controlled length fields deserialized from a session file, a crafted session file can cause nnn to write data beyond the bounds of fixed-size global buffers when loaded with the -s option. An attacker who...

libp2p: yamux connection DoS via oversized data frame

SummaryThe yamux stream multiplexer in py-libp2p does not validate incoming DATA frame lengths against the receive window before reading the frame body. Any peer that completes a standard libp2p handshake can send a single 12-byte frame claiming a 4 GB body, causing the victim's yamux read loop t...

EUVD-2026-62363

An out-of-bounds read vulnerability was found in swtpm's SWTPMNVRAMCheckHeader function. The entry guard checks the buffer length against sizeofbh, where bh is a pointer, instead of sizeofbh, the actual struct size. This allows an undersized buffer to pass validation, causing a 2-byte heap overre...

Name of the Vulnerable Software and Affected Versions nnn version 5.2 Description An Out-of-Bound write issue exists due to insufficient validation of attacker-controlled length fields during the deserialization of session files. When a crafted session file is loaded using the -s option, the...

CVE-2026-72330

A flaw was found in the Linux kernel's TLS Transport Layer Security implementation. A remote attacker could send specially crafted zero-length TLS application data records. This could cause the system to repeatedly process these empty records, blocking all subsequent legitimate data on the...

Memory Allocation with Excessive Size Value

Overview Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value via the readBytes method in src/main/java/com/rabbitmq/client/impl/ValueReader.java. An attacker can trigger a JVM OutOfMemoryError by sending an AMQP field or long string with a declared leng...

SUSE CVE-2026-68145

In the Linux kernel, the following vulnerability has been resolved: iomap: fix out-of-bounds bitmapset with zero-length range ifssetrangedirty and ifssetrangeuptodate compute lastblk as off + len - 1 iblkbits. When off is 0 and len is 0, the unsigned subtraction underflows to SIZEMAX, producing a...

GO-2026-6172 WITHDRAWN: Backend frame lengths cause pre-validation memory exhaustion in github.com/lib/pq

This report has been withdrawn with reason: "Report mistakenly added without having CVE / GHSA associated". github.com/lib/pq allocates the backend-declared PostgreSQL frame payload before applying a protocol length bound or a phase-specific message-type check. A malicious server or active networ...

CVE-2026-61634 RabbitMQ Java client accepts broker frames larger than the negotiated AMQP frame_max

The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.33.0, the AMQP connection tuning path records the negotiated AMQP framemax value, but src/main/java/com/rabbitmq/client/impl/SocketFrameHandler.java and...
