Last modified

CVE-2016-1583 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. 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.. EPSS estimates a 1.39% chance of exploitation in the next 30 days.
