  - kernel: netfilter: use-after-free in tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c
    (CVE-2017-18017)

  - The ia64 subsystem in the Linux kernel before 2.6.26 allows local users to cause a denial of service
    (stack consumption and system crash) via a crafted application that leverages the mishandling of invalid
    Register Stack Engine (RSE) state. (CVE-2006-3635)

  - drivers/media/video/videobuf-vmalloc.c in the Linux kernel before 2.6.24 does not initialize
    videobuf_mapping data structures, which allows local users to trigger an incorrect count value and
    videobuf leak via unspecified vectors, a different vulnerability than CVE-2010-5321. (CVE-2007-6761)

is installed.");
