Andrey Konovalov discovered that the SCTP implementation in the Linux kernel improperly handled validation of incoming data. A remote attacker could use this to cause a denial of service (system crash).
(CVE-2016-9555)
It was discovered that multiple memory leaks existed in the XFS implementation in the Linux kernel. A local attacker could use this to cause a denial of service (memory consumption). (CVE-2016-9685).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
