copy-fail-CVE-2026-31431-IOC

copyfail-detect 针对 CVE-2026-31431（“Copy Fail”）的检测工具包，这是一种 Linux 内核本地权限提升技术，可在不修改磁盘上文件的情况下破坏页缓存数据。 存在原因 Copy Fail 可以绕过传统的文件完整性监控，因为磁盘上的文件并未被修改。本仓库提供基于 auditd、eBPF、页缓存比对、Sigma 规则和响应文档的分层检测方案。 eBPF 监控器是保真度最高的检测器：它监视 AFALG 活动，提取 authencesn 绑定尝试，跟踪可疑的 splice 用法，并将这些事件关联为高置信度的漏洞利用链告警。 快速开始...

Astra Linux – Vulnerabilities in paramiko, libssh, libssh2, erlang, openssh

The SSH transport protocol, with certain OpenSSH extensions, found in OpenSSH versions prior to 9.6 and other products, allows remote attackers to bypass integrity checks. As a result, some packets may be omitted from the extension negotiation message. Consequently, the client and server may end ...

openssl: CMS AuthEnvelopedData Processing May Accept Forged Messages

A flaw was found in OpenSSL's Cryptographic Message Services CMS AuthEnvelopedData processing. An on-path attacker can exploit insufficient input validation on cipher and tag length fields by sending specially crafted CMS messages. This can lead to the forging of messages or bypassing integrity...

PostgreSQL 17.x < 17.11 / 18.x < 18.6 GSSAPI Improper Message Integrity Enforcement

The version of PostgreSQL installed on the remote host is 17 prior to 17.11 or 18 prior to 18.6. As such, it is potentially affected by a security bypass vulnerability: - Improper enforcement of message integrity in PostgreSQL GSSAPI support allows a user to negotiate GSSAPI contrary to pghba.con...

cmd/go: golang: Go command (cmd/go): Integrity bypass due to checksum validation flaw via malicious module proxy

A flaw was found in the Go command cmd/go. A malicious module proxy can exploit this vulnerability by bypassing the validation of module checksums. This allows the proxy to serve altered versions of the Go toolchain, which the go command may then download and execute without proper verification...
