The kernel packages contain the Linux kernel, the core of any Linux operating system.
Security Fix(es):

  • kernel: buffer overflow in IPsec ESP transformation code (CVE-2022-27666)
  • kernel: out-of-bounds read in fbcon_get_font function (CVE-2020-28915)
    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.
