A set of AppArmor vulnerabilities Qualys 发布了一份关于 AppArmor 安全模块存在多个漏洞的公告。这些漏洞被统称为“CrackArmor”，主要影响基于 Debian 的发行版等系统。 公告指出，这些漏洞包含一个“混淆代理人”缺陷，允许非特权用户通过伪文件操作安全配置文件、绕过用户命名空间限制，并在内核中执行任意代码。通过与 Sudo 和 Postfix 等工具的复杂交互，攻击者可利用这些漏洞在本地将权限提升至 root。此外，漏洞还可导致通过堆栈耗尽发起的拒绝服务攻击，以及通过越界读取绕过内核地址空间布局随机化（KASLR）。 原文链接：https://lwn.net/Articles/1062778/ #Linux#安全漏洞#AppArmor#本地提权 #AIGC Read more

PC Gamer on the scx_horoscope scheduler PC Gamer 评测了一款基于占星术的 Linux CPU 调度器 scx_horoscope。该调度器利用实时行星位置、月相（满月时任务性能据称提升 1.4 倍）和“基于星座的任务分类”来优化调度决策。 例如，关键系统进程由太阳掌管，交互任务由月亮掌管，而内存密集型应用则由木星掌管。 文章链接：https://www.pcgamer.com/hardware/this-scientifically-dubious-linux-cpu-scheduler-makes-decisions-based-on-real-time-planetary-positions-zodiac-signs-and-astrological-principles/ 项目链接：https://github.com/zampierilucas/scx_horoscope?tab=readme-ov-file#scx_horoscope---astrological-cpu-scheduler #Linux#内核#调度器#占星术#开源 #AIGC Read more

[$] More timing side-channels for the page cache Linux 内核的页面缓存时序保护机制被发现存在新漏洞。研究人员发现，攻击者可以利用这些漏洞，通过分析页面缓存的时间信息，推断出系统中哪些文件支持的页面被访问过。这可能导致信息泄露等安全问题。 早在2019年，类似的时间侧信道攻击就曾迫使内核修改了 `mincore()` 系统调用的设计，并应用了一系列补丁。当时人们认为零散的修复已经成功堵上了漏洞。然而，新的研究表明，同一类攻击仍然可行，现有的防护措施存在缺陷。 原文链接：https://lwn.net/Articles/1061743/ #Linux#内核安全#侧信道攻击#页面缓存 #AIGC Read more
