  <description>The SUSE Linux Enterprise 15 kernel was updated to receive various security and bugfixes.


The following security bugs were fixed:

- 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-2021-3347: 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-2020-25211: Fixed a buffer overflow in ctnetlink_parse_tuple_filter() which could be triggered by a local attackers by injecting conntrack netlink configuration (bnc#1176395).
- 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-2020-29569: 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-2020-0444: 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-2020-4788: Fixed an issue with IBM Power9 processors could have allowed a local user to obtain sensitive information from the data in the L1 cache under extenuating circumstances (bsc#1177666).
- CVE-2020-10781: A flaw was found in the ZRAM kernel module, where a user with a local account and the ability to read the /sys/class/zram-control/hot_add file can create ZRAM device nodes in the /dev/ directory. This read allocates kernel memory and is not accounted for a user that triggers the creation of that ZRAM device. With this vulnerability, continually reading the device may consume a large amount of system memory and cause the Out-of-Memory (OOM) killer to activate and terminate random userspace processes, possibly making the system inoperable (bnc#1173074).
- 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-2020-25639: Fixed a NULL pointer dereference via nouveau ioctl (bnc#1176846).
- 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-2020-28374: Fixed a Linux SCSI target issue (bsc#1178372).
- CVE-2020-25669: Fixed a use-after-free read in sunkbd_reinit() (bsc#1178182).
- CVE-2020-29371: An issue was discovered in romfs_dev_read in fs/romfs/storage.c where uninitialized memory leaks to userspace (bnc#1179429).
- 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-2020-11668: Fixed the mishandling of invalid descriptors in the Xirlink camera USB driver (bnc#1168952).
- CVE-2019-20934: Fixed a use-after-free in show_numa_stats() because NUMA fault statistics were inappropriately freed (bsc#1179663).
- CVE-2019-20806: Fixed a NULL pointer dereference in tw5864_handle_frame() in drivers/media/pci/tw5864/tw5864-video.c, which may cause denial of service (bnc#1172199).

- HID: Fix slab-out-of-bounds read in hid_field_extract (bsc#1180052).
