This is a kernel live patch module which is automatically loaded by the RPM post-install script to modify the code of a running kernel.

Security Fix(es):

  • kernel: race condition in net/can/bcm.c leads to local privilege escalation (CVE-2021-3609)

  • kernel: Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass RO checks (CVE-2021-22543)

  • kernel: out-of-bounds write in xt_compat_target_from_user() in net/netfilter/x_tables.c (CVE-2021-22555)

  • kernel: race condition for removal of the HCI controller (CVE-2021-32399)

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.
