DESCRIPTION

* CVE-2018-9568: Memory corruption in IPv6 to IPv4 socket cloning.

A logic error when transforming an IPv6 socket to an IPv4 socket can
result in releasing memory into the wrong cache. This flaw can result in
memory corruption.


* CVE-2018-17972: Information leak in /proc kernel stack dumps.

A failure to restrict accessing /proc/self/task/*/stack to only
root could allow an unprivileged user to get information about the
stack and its contents on another process.


* CVE-2018-18281: Information leak in mremap syscall.

A logic error in the mremap code could allow one process to access
memory of a different process.


* CVE-2018-1066: Remote denial-of-service upon CIFS session recovery.

A NULL pointer dereference when negotiating CIFS session recovery leads
to a kernel panic. A malicious remote attacker who controls the CIFS
server could exploit this bug to cause a denial-of-service.
