KRIe KRIe is a research project that aims to detect Linux Kernel exploits with eBPF. KRIe is far from being a bulletproof strategy: from eBPF related limitations to post exploitation detections that might rely on a compromised kernel to emit security events, it is clear that a motivated attacker...

usbsnoop

usbsnoop — live USB transfer sniffer from two fentry hooks A real-time, colorized feed of USB traffic system-wide — built on the two universal URB chokepoints every host-controller driver funnels through, so it works on xHCI/EHCI/OHCI/dwc alike with no per-controller tracepoints and no usbmon...

FIM-eBPF: File Integrity Monitoring with eBPF A lightweight eBPF program to monitor file creation and modification events on Linux. This tool leverages eBPF Extended Berkeley Packet Filter to trace file operations directly from the kernel, providing high-performance monitoring with minimal...

SUSE CVE-2026-98626

In the Linux kernel, the following vulnerability has been resolved: bpf: Restrict CO-RE poisoning to relocatable instructions CO-RE relocation records can name any instruction offset.

CVE-2026-98626

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. When processing Compile Once – Run Everywhere CO-RE relocation records, the kernel modifies target instructions before verifying that the instruction is an eligible relocation target. A local user can exploit this...

CVE-2026-98626

The Linux kernel contains a vulnerability in its CO-RE (Compile Once - Run Everywhere) mechanism. The bpf_core_patch_insn() function incorrectly poisons relocation targets before verifying if they are valid. This allows malformed metadata to replace critical instructions such as jumps, calls, exi...
