The kernel packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way the Linux kernel's futex subsystem handled the requeuing of certain Priority Inheritance (PI) futexes. A local, unprivileged user could use this flaw to escalate their privileges on the system. (CVE-2014-3153, Important) * A use-after-free flaw was found in the way the ping_init_sock() function of the Linux kernel handled the group_info reference counter. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-2851, Important) * Use-after-free and information leak flaws were found in the way the Linux kernel's floppy driver processed the FDRAWCMD IOCTL command. A local user with write access to /dev/fdX could use these flaws to escalate their privileges on the system. (CVE-2014-1737, CVE-2014-1738, Important) * It was found that the aio_read_events_ring() function of the Linux kernel's Asynchronous I/O (AIO) subsystem did not properly sanitize the AIO ring head received from user space. A local, unprivileged user could use this flaw to disclose random parts of the (physical) memory belonging to the kernel and/or other processes. (CVE-2014-0206, Moderate) * An out-of-bounds memory access flaw was found in the Netlink Attribute extension of the Berkeley Packet Filter (BPF) interpreter functionality in the Linux kernel's networking implementation. A local, unprivileged user could use this flaw to crash the system or leak kernel memory to user space via a specially crafted socket filter. (CVE-2014-3144, CVE-2014-3145, Moderate) * An information leak flaw was found in the way the skb_zerocopy() function copied socket buffers (skb) that are backed by user-space buffers (for example vhost-net and Xen netback), potentially allowing an attacker to read data from those buffers. (CVE-2014-2568, Low) Red Hat would like to thank Kees Cook of Google for reporting CVE-2014-3153 and Matthew Daley for reporting CVE-2014-1737 and CVE-2014-1738. Google acknowledges Pinkie Pie as the original reporter of CVE-2014-3153. The CVE-2014-0206 issue was discovered by Mateusz Guzik of Red Hat. This update also fixes the following bugs: * Due to incorrect calculation of Tx statistics in the qlcninc driver, running the 'ethtool -S ethX' command could trigger memory corruption. As a consequence, running the sosreport tool, that uses this command, resulted in a kernel panic. The problem has been fixed by correcting the said statistics calculation.
