The SUSE Linux Enterprise 15 SP2 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2021-3347: A use-after-free was discovered in the PI futexes during fault handling, allowing local users to execute code in the kernel (bnc#1181349). - CVE-2021-3348: Fixed a use-after-free in nbd_add_socket that could be triggered by local attackers (with access to the nbd device) via an I/O request at a certain point during device setup (bnc#1181504). - CVE-2021-20177: Fixed a kernel panic related to iptables string matching rules.
