    Security Fix(es):
    
    * Kernel: page cache side channel attacks (CVE-2019-5489)
    
    * kernel: Salsa20 encryption algorithm does not correctly handle
    zero-length inputs allowing local attackers to cause denial-of-service
    (CVE-2017-17805)
    
    * kernel: Unprivileged users able to inspect kernel stacks of arbitrary
    tasks (CVE-2018-17972)
    
    * kernel: hw: Spectre SWAPGS gadget vulnerability (CVE-2019-1125)
    
    For more details about the security issue(s), including the impact, a CVSS
    score, acknowledgments, and other related information, refer to the CVE
    page(s) listed in the References section.
    
    Bug Fix(es):
    
    * OOPS with Null Pointer exception in v4l2_ctrl_query_menu when second arg
    of function is NULL (BZ#1647975)

    * kernel crash after running user space script (BZ#1663262)
    
    * RHEL-6.10: Don't report the use of retpoline on Skylake as vulnerable
    (BZ#1666102)
    
    * Bad pagetable: 000f “*pdpt = 0000000000000000 *pde = 0000000000000000” 
    RHEL 6 32bit (BZ#1702782)
    
    * fs/binfmt_misc.c: do not allow offset overflow [6.10.z] (BZ#1710149)
    
    * Wrong spectre backport causing linux headers to break compilation of 3rd
    party packages (BZ#1722185)
