CVE-2014-3122

Status Candidate

Overview

The try_to_unmap_cluster function in mm/rmap.c in the Linux kernel before 3.14.3 does not properly consider which pages must be locked, which allows local users to cause a denial of service (system crash) by triggering a memory-usage pattern that requires removal of page-table mappings.

Red Hat Security Advisory 2014-1392-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A NULL pointer dereference flaw was found in the way the Linux kernel's Stream Control Transmission Protocol implementation handled simultaneous connections between the same hosts. A remote attacker could use this flaw to crash the system. An integer overflow flaw was found in the way the Linux kernel's Frame Buffer device implementation mapped kernel memory to user space via the mmap syscall. A local user able to access a frame buffer device file could possibly use this flaw to escalate their privileges on the system.

Red Hat Security Advisory 2014-0557-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A race condition leading to a use-after-free flaw was found in the way the Linux kernel's TCP/IP protocol suite implementation handled the addition of fragments to the LRU list under certain conditions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system by sending a large amount of specially crafted fragmented packets to that system.
