6. IonStack part II: GhostLock, a stack-UAF that has existed in ALL Linux distributions for 15 years4.0/5
GhostLock (CVE-2026-43499) is a use-after-free vulnerability in the Linux kernel’s rtmutex (real-time mutex) code, specifically the remove_waiter() routine used on the slow-lock and proxy-lock rollback paths. Because remove_waiter() operated on the current task instead of waiter::task, it left a dangling pointer that a local, unprivileged attacker can abuse to escalate privileges or trigger a denial of service. The flaw has existed in every major distribution since kernel 2.6.39 (2011), scores CVSS 3.1 7.8 (High), and is fixed in kernel 6.6.140+, 6.12.86+, 6.18.27+, 7.0.4+ and 7.1. The nebusec.ai (VEGA) writeup provides the full technical exploitation analysis.
- Comprehensive technical breakdown
- High impact vulnerability
- Clear demonstration of exploit
- Highly technical content
- Limited to Linux kernel security
