CVE-2026-63449

Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. From 8.0.0 until 8.0.6, the SIP parser in rust/src/sip/parser.rs stores request and response body lengths in 16-bit fields. A SIP body larger than 65,536 bytes can truncate the...

CVE-2026-63449

Suricata versions 8.0.0 through 8.0.6 are affected by a SIP parser flaw in rust/src/sip/parser.rs, where request and response body lengths are stored in 16-bit fields . A SIP body exceeding 65,536 bytes truncates the stored length, causing frame:request.body or frame:response.body to omit part of...

Linux Distros Unpatched Vulnerability : CVE-2026-90245

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - fbdev: kyro: Validate overlay viewport coordinates The overlay viewport end coordinates are computed from the viewport origin and dimensions using 32-bit unsign...

EUVD-2026-81838

In the Linux kernel, the following vulnerability has been resolved: fbdev: kyro: Validate overlay viewport coordinates The overlay viewport end coordinates are computed from the viewport origin and dimensions using 32-bit unsigned arithmetic. Large input values can cause these calculations to wra...

CVE-2026-19667

A flaw was found in bind9's named component. A remote attacker, by sending a specially crafted DNS negative answer of exactly 65536 bytes from an authoritative server, can cause a 16-bit length truncation. This results in a zero-byte negative cache entry. When named attempts to read this invalid...

CVE-2026-19667

CVE-2026-19667 is a remote assertion failure in the BIND 9 named daemon, caused by a 16-bit length truncation in dns_ncache_add(). When an attacker-controlled authoritative server returns a negative answer of exactly 65536 bytes , the negative cache entry is stored as 0 bytes; reading that entry ...

CVE-2025-65018_Exploit_Challenge

CVE-2025-65018 CTF 挑战："PNG Panic" 该挑战基于 libpng 中的真实缓冲区溢出漏洞（特别是在处理 16 位隔行扫描图像时，简化 API pngimagefinishread 中的问题）。 🚩 挑战目标 给定一个易受攻击的二进制文件 victim，它使用静态链接的、存在漏洞的 libpng 版本。该应用程序将一个名为 exploit.png 的 PNG 文件读入缓冲区。 你的目标是构造一个恶意的 PNG 文件，触发堆溢出，覆盖 Logger 结构体（位于图像缓冲区之后）中的函数指针，将执行重定向到 win 函数，从而生成一个 shell。 🛠️ 搭建与构建...

Astra Linux – Vulnerability in libstb

A issue was discovered in stbstbimage.h 2.27. The PNM loader incorrectly interpreted 16-bit PGM files as 8-bit when converting them to RGBA format. This led to a buffer overflow when the result was re-interpreted as a 16-bit buffer. An attacker could potentially use stbimage to crash a service, o...

CVE-2026-80978

In the Linux kernel, the following vulnerability has been resolved: net: cap advertised IP tunnel headroom IP tunnel devices derive their advertised neededheadroom from lower output devices. A stack of user-created devices can make the derived value larger than the 16-bit skb header offsets can...

UBUNTU-CVE-2026-80978

In the Linux kernel, the following vulnerability has been resolved: net: cap advertised IP tunnel headroom IP tunnel devices derive their advertised neededheadroom from lower output devices. A stack of user-created devices can make the derived value larger than the 16-bit skb header offsets can...

CVE-2026-80978

CVE-2026-80978 affects the Linux kernel networking subsystem, specifically the IP tunnel devices. When a local attacker stacks user-created IP tunnel devices, the derived needed_headroom can exceed the 16-bit skb header offset range, causing those offsets to wrap during skb head expansion. The fi...
