CVE-2026-31393 Bluetooth: L2CAP: Validate L2CAP_INFO_RSP payload length before access
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: Validate L2CAPINFORSP payload length before access l2capinformationrsp checks that cmdlen covers the fixed l2capinforsp header type + result, 4 bytes but then reads rsp-data without verifying that the payload is...
CVE-2026-23457
CVE-2026-23457 affects the Linux kernel netfilter nf_conntrack_sip parser (sip_help_tcp). The issue arises from parsing the SIP Content-Length header: the code uses simple_strtoul() return value (unsigned long) but stores it in an unsigned int clen, allowing truncation on 64-bit systems when Cont...

CVE-2026-23455
TL;DR : CVE-2026-23455 is a Linux kernel vulnerability in netfilter nf_conntrack_h323, fixed by adding a check so the decoded length remains positive after subtracting the protocol discriminator. Affected component : Linux kernel, nf_conntrack_h323 DecodeQ931() UserUserIE path. Root cause : The d...
CVE-2026-23455 netfilter: nf_conntrack_h323: check for zero length in DecodeQ931()
In the Linux kernel, the following vulnerability has been resolved: netfilter: nfconntrackh323: check for zero length in DecodeQ931 In DecodeQ931, the UserUserIE code path reads a 16-bit length from the packet, then decrements it by 1 to skip the protocol discriminator byte before passing it to...

JLSEC-2026-56
Missing validation of multibyte character length in PostgreSQL text manipulation allows a database user to issue crafted queries that achieve a buffer overrun. That suffices to execute arbitrary code as the operating system user running the database. Versions before PostgreSQL 18.2, 17.8, 16.12,...
Swift Crypto: X-Wing HPKE Decapsulation Accepts Malformed Ciphertext Length
Summary The X-Wing decapsulation path accepts attacker-controlled encapsulated ciphertext bytes without enforcing the required fixed ciphertext length. The decapsulation call is forwarded into a C API, which expects a compile-time fixed-size ciphertext buffer of 1120 bytes. This creates an FFI...

Name of the Vulnerable Software and Affected Versions HiOS versions prior to 08.1.00 HiOS versions prior to 07.1.01 Description A denial of service issue exists in the EtherNet/IP stack due to improper handling of packet length fields. Remote attackers can cause the device to crash or hang by...
Linux kernel 安全漏洞
The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from a lack of length checking in the DecodeQ931 function, potentially leading to out-of-bounds reads...
CocoaMQTT: Denial of Service via Reachable Assertion in `PUBLISH` Packet Parsing
A vulnerability exists in the packet parsing logic of CocoaMQTT that allows an attacker or a compromised/malicious MQTT broker to remotely crash the host iOS/macOS/tvOS application. The vulnerability is located in Source/FramePublish.swift during the extraction of the Topic string from the incomi...

GHSA-Q2WW-5357-X388 Rack has Content-Length mismatch in Rack::Files error responses
Summary Rack::Filesfail sets the Content-Length response header using Stringsize instead of Stringbytesize. When the response body contains multibyte UTF-8 characters, the declared Content-Length is smaller than the number of bytes actually sent on the wire. Because Rack::Files reflects the...
