CVE-2026-89902

This Linux kernel vulnerability affects the LoongArch kprobe subsystem. Because LoongArch uses break 11 for kprobe breakpoints, an ordinary userspace breakpoint can reach kprobe_singlestep_handler() with no active probe. The handler calls preempt_enable_no_resched() before checking for a probe, c...

In the Linux kernel, the following vulnerability has been resolved: LoongArch: Avoid preempt count underflow without probe LoongArch uses break 11 for the breakpoint placed after an instruction that Kprobes executes out of line. Since userspace can issue the same break instruction, dobp can reach...

IPCDump

ipcdump 公告文章 ipcdump 是一个用于跟踪 Linux 上进程间通信（IPC）的工具。它涵盖了大多数常见的 IPC 机制——管道、FIFO、信号、Unix 套接字、基于环回的网络以及伪终端。它是调试多进程应用的有用工具，也是理解系统中不同组件如何相互通信的简单方式。ipcdump 可以跟踪通信的元数据以及内容，特别适合跟踪短生命周期进程之间的 IPC，而这在使用传统调试工具（如 strace 或 gdb）时可能很困难。它还具备一些基本的过滤功能，帮助您筛选大量事件。 ipcdump 收集的大部分信息来自放置在关键内核函数的 kprobes 和 tracepoints 上的...

CVE-2026-80611

A flaw was found in the Linux kernel's Advanced Configuration and Power Interface ACPI processor idle functionality.
