CVE-2016-6224: Input Validation
First published: Fri Jul 22 2016(Updated: )
ecryptfs-setup-swap in eCryptfs does not prevent the unencrypted swap partition from activating during boot when using GPT partitioning on a (1) NVMe or (2) MMC drive, which allows local users to obtain sensitive information via unspecified vectors. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-8946.
