Details

A stack overflow was discovered in the the microcode loader for the intel
x86 platform. A local attacker could exploit this flaw to cause a denial of
service (kernel crash) or to potentially execute code with kernel
privileges. (CVE-2015-2666)

It was discovered that the Linux kernel’s IPv6 networking stack has a flaw
that allows using route advertisement (RA) messages to set the β€˜hop_limit’
to values that are too low. An unprivileged attacker on a local network
could exploit this flaw to cause a denial of service (IPv6 messages
dropped). (CVE-2015-2922)
