A flaw was found in the way pi to pi futex requeueing was handled.
A local unprivileged user can use this flaw to increase their privileges on the system.
A flaw was found in the way Linux kernel's floppy driver treated userspace provided data in certain error code path while processing FDRAWCMD ioctl command. An local user with write access to /dev/fdX could use this flaw to kfree() arbitrary data. (CVE-2014-1737)
It was found that Linux kernel's floppy driver leaked internal kernel memory addresses to userspace during processing of FDRAWCMD ioctl command. An local user with write access to /dev/fdX could use this flaw to get information about kernel heap arrangment. (CVE-2014-1738)
An local user with write access to /dev/fdX could use these two flaws (CVE-2014-1737 in combination with CVE-2014-1738) to escalate their privileges on the system.

A flaw was found in the way iommu mapping failures were handled in kvmiommumappages() function in the Linux kernel (introduced by the fix for CVE-2014-3601).
A privileged user in the guest could use this flaw to crash the host in case the guest has access to passed in device.

DISPUTED Multiple integer overflows in the lzo1xdecompresssafe function in lib/lzo/lzo1xdecompresssafe.c in the LZO decompressor in the Linux kernel before 3.15.2 allow context-dependent attackers to cause a denial of service (memory corruption) via a crafted Literal Run. NOTE: the author of the LZO algorithms says "the Linux kernel is not affected; media hype."
A NULL pointer dereference flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled simultaneous connections between the same hosts. A remote attacker could use this flaw to crash the system.
