  • kernel: Exploitable memory corruption due to UFO to non-UFO path switch (CVE-2017-1000112)

  • kernel: Out-of-bounds write via userland offsets in ebt_entry struct in netfilter/ebtables.c (CVE-2018-1068)

  • kernel: Memory corruption due to incorrect socket cloning (CVE-2018-9568)

  • kernel: Missing check in fs/inode.c:inode_init_owner() does not clear SGID bit on non-directories for non-members (CVE-2018-13405)

  • kernel: Use-after-free due to race condition in AF_PACKET implementation (CVE-2018-18559)

  • Kernel: page cache side channel attacks (CVE-2019-5489)

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.
