The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the Linux kernel before 4.6.3 allows local users to gain privileges or cause a denial of service (stack memory consumption) via vectors involving crafted mmap calls for /proc pathnames, leading to recursive pagefault handling.

Exploit prediction (EPSS)

1.39% probability of exploitation in the next 30 days, higher than 72% of all scored CVEs.
