The SUSE Linux Enterprise 15 SP2 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2020-25285: A race condition between hugetlb sysctl handlers in mm/hugetlb.c could be used by local attackers to corrupt memory, cause a NULL pointer dereference, or possibly have unspecified other impact (bnc#1176485). - CVE-2020-16120: Fixed permission check to open real file when using overlayfs.
