Saint Towelroot, Who Brought Root With a Towel
Patron of Android phones to be freed, the futex call, and one-click roots on a Sunday night.
Life
In June 2014 George Hotz released Towelroot, an app that with a single tap granted root on a great many Android phones. It exploited CVE-2014-3153, a flaw in the Linux kernel's futex_requeue function reported by Pinkie Pie: the call did not check that two futexes were different, opening the way to privilege escalation. Born to free phones, the same flaw could also serve whoever wanted to take them over.
Prayer
O Saint Towelroot, who grants root with a towel, let our futex always tell one address from another. Amen.
How to celebrate
Celebrated by installing a kernel updated after June 2014 and always knowing where your towel is.
A towel, and the phone is yours.
