🐧GhostLock (CVE-2026-43499): a 15-year-old Linux kernel vulnerability that affects every distribution. Desktop, server, Android, IoT, embedded. $92,337 Google kernelCTF bounty.
https://github.com/NebuSec/CyberMeowfia/tree/main/IonStack/CVE-2026-43499
A stack-UAF in the rtmutex subsystem. remove_waiter() uses current instead of waiter::task during proxy-lock rollback in futex_requeue(), leaving a dangling pointer to freed kernel stack memory. No special kernel modules needed, only CONFIG_FUTEX_PI which is enabled on every distro.
Nebula Security (NebuSec) turned it into a 97% stable privilege escalation and container escape. The exploit chains a dangling pointer into an arbitrary address write, hijacks a function table for control flow, and achieves root in about 5 seconds. Found by VEGA, their AI vulnerability scanner.
Part of IonStack, the first browser-to-kernel full-chain RCE on Android 17: CVE-2026-10702 (Firefox IonMonkey JIT 0-day, near 100% success rate) chained with GhostLock for kernel LPE.
Present since Linux 2.6.39 (2011). Fixed in Linux 7.1. Full exploit code published on GitHub.
