The SUSE Linux Enterprise 12 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-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).

CVE-2020-0444: Fixed a bad kfree due to a logic error in audit_data_to_entry (bnc#1180027).

CVE-2020-0465: Fixed multiple missing bounds checks in hid-multitouch.c that could have led to local privilege escalation (bnc#1180029).

CVE-2020-0466: Fixed a use-after-free due to a logic error in do_epoll_ctl and ep_loop_check_proc of eventpoll.c (bnc#1180031).

CVE-2020-15436: Fixed a use after free vulnerability in fs/block_dev.c which could have allowed local users to gain privileges or cause a denial of service (bsc#1179141).

CVE-2020-27068: Fixed an out-of-bounds read due to a missing bounds check in the nl80211_policy policy of nl80211.c (bnc#1180086).

CVE-2020-27777: Fixed a privilege escalation in the Run-Time Abstraction Services (RTAS) interface, affecting guests running on top of PowerVM or KVM hypervisors (bnc#1179107).

CVE-2020-27786: Fixed an out-of-bounds write in the MIDI implementation (bnc#1179601).

CVE-2020-27825: Fixed a race in the trace_open and buffer resize calls (bsc#1179960).

CVE-2020-29660: Fixed a locking inconsistency in the tty subsystem that may have allowed a read-after-free attack against TIOCGSID (bnc#1179745).

CVE-2020-29661: Fixed a locking issue in the tty subsystem that allowed a use-after-free attack against TIOCSPGRP (bsc#1179745).

CVE-2020-28974: Fixed a slab-out-of-bounds read in fbcon which could have been used by local attackers to read privileged information or potentially crash the kernel (bsc#1178589).

CVE-2020-28915: Fixed a buffer over-read in the fbcon code which could have been used by local attackers to read kernel memory (bsc#1178886).

CVE-2020-25669: Fixed a use-after-free read in sunkbd_reinit() (bsc#1178182).

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-2020-15437: Fixed a NULL pointer dereference which could have allowed local users to cause a denial of service (bsc#1179140).

CVE-2020-36158: Fixed a potential remote code execution in the Marvell mwifiex driver (bsc#1180559).

CVE-2020-27673: Fixed an issue where rogue guests could have caused denial of service of Dom0 via high frequency events (XSA-332 bsc#1177411)

CVE-2019-20934: Fixed a use-after-free in show_numa_stats() because NUMA fault statistics were inappropriately freed (bsc#1179663).

CVE-2019-19063: Fixed two memory leaks in the rtl_usb_probe() which could eventually have allowed attackers to cause a denial of service (memory consumption) (bnc#1157298 ).

CVE-2019-6133: Fixed an issue where the ‘start time’ protection mechanism could have been bypassed and therefore authorization decisions are improperly cached (bsc#1128172).

The update package also includes non-security fixes. See advisory for details.
