The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

  • kernel: Integer overflow in Intel® Graphics Drivers (CVE-2020-12362)

  • kernel: Local buffer overflow in ctnetlink_parse_tuple_filter in net/netfilter/nf_conntrack_netlink.c (CVE-2020-25211)

  • kernel: malicious USB devices can lead to multiple out-of-bounds write (CVE-2019-19532)

  • kernel: ICMP rate limiting can be used for DNS poisoning attack (CVE-2020-25705)

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):

  • memcg: mem_cgroup_idr can be updated in an uncoordinated manner which can lead to corruption (BZ#1931901)

  • Kernel experiences panic in update_group_power() due to division error even with Bug 1701115 fix (BZ#1961624)
