Description:
 A potential vulnerability in the AMD extension to Linux "hwmon" service may
 allow an attacker to use the Linux-based Running Average Power Limit (RAPL)
 interface to show various side channel attacks. In line with industry
 partners, AMD has updated the RAPL interface to require privileged access.
Ubuntu-Description:
 It was discovered that the AMD Running Average Power Limit (RAPL) driver in
 the Linux kernel did not properly restrict access to power data. A local
 attacker could possibly use this to expose sensitive information.
