#kernelexploit — Public Fediverse posts

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.

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.

Linux admins should prioritize patching immediately.
