The SUSE Linux Enterprise 12 SP5 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-2021-20177: Fixed a kernel panic related to iptables string matching rules. A privileged user could insert a rule which could lead to denial of service (bnc#1180765). - CVE-2021-0342: In tun_get_user of tun.c, there is possible memory corruption due to a use after free. This could lead to local escalation of privilege with System execution privileges required. (bnc#1180812) - CVE-2020-27835: A use-after-free in the infiniband hfi1 driver was found, specifically in the way user calls Ioctl after open dev file and fork. A local user could use this flaw to crash the system (bnc#1179878). - CVE-2020-25639: Fixed a NULL pointer dereference via nouveau ioctl (bnc#1176846). - CVE-2020-29569: Fixed a potential privilege escalation and information leaks related to the PV block backend, as used by Xen (bnc#1179509). - CVE-2020-29568: Fixed a denial of service issue, related to processing watch events (bnc#1179508). - CVE-2020-25211: Fixed a flaw where a local attacker was able to inject conntrack netlink configuration that could cause a denial of service or trigger the use of incorrect protocol numbers in ctnetlink_parse_tuple_filter (bnc#1176395).
