Vulnerability from variot

The kernel in Apple iOS before 9.3.5 allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app. Apple iOS is prone to a memory-corruption vulnerability. Failed exploit attempts may result in a denial-of-service condition. Versions prior to Apple iOS 9.3.5 are vulnerable. Kernel is one of the kernel components. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512
