CVE-2017-17807
First published: Fri Dec 08 2017(Updated: )
Linux Kernel could allow a local authenticated attacker to bypass security restrictions, caused by omitting an access-control check when adding a key to the current task's default request-key keyring in the KEYS subsystem. By using a sequence of specially-crafted system calls, an attacker could exploit this vulnerability to add keys to a keyring with only Search permission.
