Ubuntu Security Notice 3343-1 - USN 3335-1 fixed a vulnerability in the Linux kernel. However, that fix introduced regressions for some Java applications. This update addresses the issue. It was discovered that a use-after-free vulnerability in the core voltage regulator driver of the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
