TID-The-Instant-Destroyer

TID — 即时销毁器 针对基于缓存的旁路攻击防护领域的独立安全研究。 概述 TID 是一种专用协议，旨在在使用后立即从 CPU 缓存层（$L1、L2$ 和 $L3$）中消除敏感数据残留（例如加密密钥）。它解决了数据在系统内存（RAM）中被擦除后仍存在于硬件结构中的关键安全漏洞。 主要成就 已验证的防御： 有效缓解 Flush+Reload 及类似的微架构旁路攻击。 可衡量的性能： 未受保护的访问： 78 CPU 周期（缓存命中）。 TID 保护的访问： 286 CPU 周期（缓存未命中）。 安全边际： 提供 3.7 倍延迟屏障 ，成功迷惑潜在攻击者。 硬件级精度： 利用优化的 CPU...

Spectre 攻击示例 使用 2018 年 1 月 2 日披露的“Spectre”漏洞利用的示例（CVE-2017-5753 和 CVE-2017-5715） Spectre 打破了不同应用程序之间的隔离。它允许攻击者诱骗遵循最佳实践的无错误程序泄露其秘密。事实上，这些最佳实践的安全性检查反而增加了攻击面，并可能使应用程序更容易受到 Spectre 攻击。 Spectre 论文 - Spectre 论文及代码来源 语言 C 语言，使用以下库： stdio.h stdint.h intrin.h - 用于 rdtscp 和 clflush 示例的功能是什么？ 我们将文本 "The...

CVE-2016-5195

记录仅以学习为目的，禁止用于非法用途 原理 该漏洞的原理是依靠并发刷写脏页，使原本只读权限的文件内容发生变更 如果被修改的文件为root所属且具备SUID权限，那么就可以利用其进行提权 影响范围 在2016年10月前被编译的且版本在2.6.22 到 4.8.3之间的内核，因为2016年10月后的大概率被打补丁了 务必是Ext文件系统，如果是XFS文件系统，就会触发xfs只读页断言，而后系统重启，变成DDos攻击了 工具代码（dirtycowfilepayload.c） include include include include include include include...

SUSE CVE-2026-97928

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: skip the VMID 0 flush for VRAM Clear-on-release only runs on VRAM, which amdgputtmmapbuffer reaches via its direct MC address without programming a GART window, yet the wipe still forces a VMID 0 flush. On GFX11 e.g...

CVE-2026-97928

A flaw was found in the AMD GPU amdgpu driver within the Linux kernel. When clearing video memory VRAM upon deallocation, the driver performs an unnecessary virtual memory flush operation. A local user can trigger this flaw during graphics memory operations, causing the graphics processing unit G...
