Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

Remotely or locally exploitable? This is very lacking on information.

If any of these were remotely exploitable it would be getting much louder and more urgent news. Local privilege escalation bugs are encountered all the time.

If they were bugs of consequence you could expect each one to get it's own domain with a scary name and a logo.
