Andrey Konovalov discovered a race condition in the UDP Fragmentation Offload (UFO) code in the Linux kernel. A local attacker could use this to cause a denial of service or execute arbitrary code.
(CVE-2017-1000112)
Andrey Konovalov discovered a race condition in AF_PACKET socket option handling code in the Linux kernel. A local unprivileged attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2017-1000111).
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.
