* Rebase to RHEL6u10 kernel 2.6.32-754.6.3.el6
* '''[Important]''' A flaw named FragmentSmack was found in the way the Linux kernel handled reassembly of fragmented IPv4 and IPv6 packets. A remote attacker could use this flaw to trigger time and calculation expensive fragment reassembly algorithm by sending specially crafted packets which could lead to a CPU saturation and hence a denial of service on the system. (CVE-2018-5391)
* '''[Important]''' An integer overflow flaw was found in the Linux kernel's create_elf_tables() function. An unprivileged local user with access to SUID (or otherwise privileged) binary could use this flaw to escalate their privileges on the system (Mutagen Astronomy). (CVE-2018-14634)
* '''[Low]''' The Linux Kernel imposes a size restriction on the arguments and environmental strings passed through RLIMIT_STACK/RLIMIT_INFINITY, but does not take the argument and environment pointers into account, which allows attackers to bypass this limitation. (CVE-2017-1000365)
* Under certain circumstances, ploop could crash after failed execution of kernel thread. (PSBM-88559)
* Under certain circumstances, Acronis Backup could trigger host crash in blk_cbt_update_size(). (PSBM-88570)
* Under certain circumstances, host could crash inside Acronis snumbd driver. (PSBM-88575)
* Under certain circumstances, Acronis Backup could trigger host hard lockup in __cbt_flush_cpu_cache. (PSBM-89323)
* Fixed locking in blk_release_queue() that led to hard lockup in blk_throtl_drain() (was broken in 2.6.32-754.6.3.el6 RHEL6 kernel). (PSBM-89391, RHBZ #1638926)
