CVE-2025-40019-POC

CVE-2025-40019 概念验证 CVE-2025-40019 是加密盐扇区初始化向量机制（crypto/essiv.c）中的一个漏洞，该机制对关联认证数据（AAD）长度相对于初始化向量（IV）大小的验证不足，导致越界内存访问。 此仓库中的代码仅为漏洞触发程序，但该漏洞易于利用。 KernelCTF 参赛记录 我在 kernelctf 的电子表格中发现了这个漏洞 链接。由于该漏洞没有相关的博客文章或 PoC，我决定探索 Linux 内核的加密子系统，以查明问题原因。 背景：磁盘加密理论与 ESSIV 要理解 ESSIV 的必要性，我们必须先了解数据在磁盘上的存储方式。磁盘加密（如...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Bridge: brndsend: Validates the lengths of ND options. The brndsend function checks the ND options based on the lengths provided for those options. A malformed option may cause the parser to progress beyond the calculated option...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: openvswitch: validate MPLS set/setmasked payload length The validateset function accepts OVSKEYATTRMPLS as a variable-sized payload for SET/SETMASKED actions. In action handling, OVS expects fixed-size MPLS key data struct...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: In the ofmodalias function, we can pass the str and len parameters. This could lead to a kernel oops in vsnprintf, as the function only allows passing a NULL pointer when the length is also 0. Additionally, we need to filter out...
