Red Hat Security Advisory 2014-0771-01 - 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 futexes. A local, unprivileged user could use this flaw to escalate their privileges on the system. A flaw was found in the way the Linux kernel's floppy driver handled user space provided data in certain error code paths while processing FDRAWCMD IOCTL commands. A local user with write access to /dev/fdX could use this flaw to free (using the kfree() function) arbitrary kernel memory. Various other issues were also addressed.

Red Hat Security Advisory 2014-0100-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way the Linux kernel's TCP/IP protocol suite implementation handled sending of certain UDP packets over sockets that used the UDP_CORK option when the UDP Fragmentation Offload feature was enabled on the output device. A local, unprivileged user could use this flaw to cause a denial of service or, potentially, escalate their privileges on the system. A flaw was found in the way the perf_trace_event_perm() function in the Linux kernel checked permissions for the function tracer functionality. An unprivileged local user could use this flaw to enable function tracing and cause a denial of service on the system.

Mandriva Linux Security Advisory 2013-291 - Multiple vulnerabilities has been found and corrected in the Linux kernel. The Linux kernel before 3.12.2 does not properly use the get_dumpable function, which allows local users to bypass intended ptrace restrictions or obtain sensitive information from IA64 scratch registers via a crafted application, related to kernel/ptrace.c and arch/ia64/include/asm/processor.h. The perf_trace_event_perm function in kernel/trace/trace_event_perf.c in the Linux kernel before 3.12.2 does not properly restrict access to the perf subsystem, which allows local users to enable function tracing via a crafted application. Multiple integer overflows in Alchemy LCD frame-buffer drivers in the Linux kernel before 3.12 allow local users to create a read-write memory mapping for the entirety of kernel memory, and consequently gain privileges, via crafted mmap operations, related to the au1100fb_fb_mmap function in drivers/video/au1100fb.c and the au1200fb_fb_mmap function in drivers/video/au1200fb.c. Various other issues have also been addressed.
