[USN-3052-1] Linux kernel vulnerabilities

Severity Medium
Affected Packages 9
CVEs 2
Info Packages Vulnerabilities

Several security issues were fixed in the kernel.

It was discovered that the keyring implementation in the Linux kernel did
not ensure a data structure was initialized before referencing it after an
error condition occurred. A local attacker could use this to cause a denial
of service (system crash). (CVE-2016-4470)

Kangjie Lu discovered an information leak in the netlink implementation of
the Linux kernel. A local attacker could use this to obtain sensitive
information from kernel memory. (CVE-2016-5243)
