type: security
subject: Updated kernel-linus packages fix security vulnerabilities
CVE:
 - CVE-2021-28711
 - CVE-2021-28712
 - CVE-2021-28713
 - CVE-2021-28714

     - kernel-linus-5.15.11-1.mga8
description: |
  This kernel-linus update is based on upstream 5.15.11 and fixes atleast the
  following security issues:

  Potentially malicious XEN PV backends can cause guest DoS due to unhardened
  frontends in the guests, even though this ought to have been prevented by
  containing them within a driver domain. This update fixes the issue tracked
  as XSA-391: blkfront (CVE-2021-28711), netfront (CVE-2021-28712),
  hvc_xen (CVE-2021-28713).

  The Linux kernel's xen-netback backend driver can be forced by guests to
  queue arbitrary amounts of network data, finally causing an out of memory
  situation in the domain the backend is running in (usually dom0). This
  update fixes the issues tracked as XSA-392 (CVE-2021-28714, CVE-2021-28715).

  For other upstream fixes, see the referenced changelogs.
