  1. New Linux kernel flaw gives attackers root access. Patch now to avoid compromise.
    #LinuxSecurity #KernelExploit

  2. A Windows 10 kernel off‑by‑one in the PagedPool allocator was showcased at WCTF 2018. By corrupting an I/O request packet the exploit gains arbitrary write in kernel space, opening the door to local privilege escalation or remote code execution. Microsoft patched it quickly, but the demo reminds us how subtle memory‑management bugs can break system trust.

  3. Critical Linux kernel vulnerability “Fragnesia” allows local users to gain root privileges without a race condition.

    Researchers warn the exploit can corrupt cached binaries in memory, persist until reboot/cache flush, and already has a public PoC on GitHub.

  7. The USB Attack: A Tiny Device, A Huge Risk
    This vulnerability revolves around a Physical Access Vector (PAV) involving a malicious USB device. The attacker planted a USB stick with malicious firmware into the target computer's USB port, allowing it to execute arbitrary code when connected. The device exploited a flaw in the USB Mass Storage Device (MSC) protocol, enabling it to bypass driver restrictions. The attacker crafted the firmware to mimic a removable drive, which was unrecognized by the operating system and thus evaded antivirus scanning. Upon insertion, the malicious firmware triggered a built-in exploit, taking advantage of a kernel vulnerability to gain system-level access. The impact of this vulnerability is severe, as it allows unauthorized access, data theft, and malware injection. The researcher earned $5,000 for reporting this critical issue. Proper remediation involves securing USB ports with hardware restrictions and implementing firmware-level whitelisting to prevent unauthorized devices from executing arbitrary code. Key lesson: Physical access can lead to critical security breaches, making it essential to secure USB ports. #BugBounty #Cybersecurity #PAV #PhysicalAccess #KernelExploit
