CVE-2011-3442
The kernel in Apple iOS before 5.0.1 does not ensure the validity of flag combinations for an mmap system call, which allows local users to execute arbitrary unsigned code via a crafted app.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.36%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
