Red Hat Security Advisory 2014-0981-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. 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. A NULL pointer dereference flaw was found in the way the futex_wait_requeue_pi() function of the Linux kernel's futex subsystem handled the requeuing of certain Priority Inheritance futexes. A local, unprivileged user could use this flaw to crash the 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. It was found that the Linux kernel's ptrace subsystem allowed a traced process' instruction pointer to be set to a non-canonical memory address without forcing the non-sysret code path when returning to user space. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system.

A local user could exploit this flaw to gain administrative privileges. It was discovered that an information leak in the Linux kernel's media- device driver. A local attacker could exploit this flaw to obtain sensitive information from kernel memory. A bounds check error was discovered in the socket filter subsystem of the Linux kernel. A local user could exploit this flaw to cause a denial of service (system crash) via crafted BPF instructions. Various other issues were also addressed.
