Hunt-Sleeping-Beacons

Hunt-Sleeping-Beacons This project is mostly a callstack scanner which tries to identify IOCs indicating an unpacked or injected C2 agent. All checks are based on the observation that C2 agents wait between their callbacks causing the beacons thread to idle and this tool aims to analyze what...

CVE-2026-90338

A flaw was found in the Linux kernel's amba-pl011 serial driver. When the pl011consolewriteatomic function is called from an atomic context, such as during a printk operation on a PREEMPTRT kernel, it attempts to acquire a sleeping lock. This action is forbidden in an atomic context and can lead ...

CVE-2026-98223

The Linux kernel contains a vulnerability where Fault-around can map ready dropbehind folios without undergoing the standard page-cache lookup. Because a mapping represents a competing cached user, the system should retain the folio rather than forcibly unmapping it upon writeback completion. If ...
