IPCDump
ipcdump Announcement post ipcdump is a tool for tracing interprocess communication IPC on Linux. It covers most of the common IPC mechanisms -- pipes, fifos, signals, unix sockets, loopback-based networking, and pseudoterminals. It's a useful tool for debugging multi-process applications, and it'...
CVE-2026-98888
A flaw was found in the Linux kernel's arm64 kprobes subsystem. When tracing or performance monitoring tools trigger a secondary probe while an initial probe is executing its single-step instruction, the kernel treats the event as unrecoverable and corrupts interrupt state tracking. A local user...
CVE-2026-98856
A flaw was found in the Linux kernel's kernel probes kprobes tracing subsystem. When arming an optimized probe near an inactive probe, the overlap detection check fails to identify an active jump instruction. A privileged local user can exploit this issue by registering specific overlapping...
DEBIAN-CVE-2026-98888
In the Linux kernel, the following vulnerability has been resolved: arm64: kprobes: Allow reentering kprobes while single-stepping A kprobe can be hit while another kprobe is in KPROBEHITSS state. This can happen when tracing or perf code runs from the debug exception path while the first kprobe ...

CVE-2026-98888
The Linux kernel (arm64 architecture) contains a flaw where kprobes are incorrectly treated as unrecoverable when hit while in a KPROBE_HIT_SS state. This occurs when tracing or perf code runs from the debug exception path during out-of-line single-step execution. The issue causes the kernel to l...

Linux Distros Unpatched Vulnerability : CVE-2026-98530
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - kprobes: Fix permanent hang when flushing the kprobe optimizer Writing 0 to /proc/sys/debug/kprobes- optimization while a kprobe is jump-optimized never returns...
CVE-2026-98530
A flaw was found in the Linux kernel's kprobes subsystem. A privileged local user could trigger improper synchronization when disabling or flushing probe optimization, causing the process to hang indefinitely while holding an internal lock. This issue can make administrative interfaces...
