The SUSE Linux Enterprise 12 SP5 kernel was updated. The following security bugs were fixed: - CVE-2019-15126: Fixed a vulnerability in Broadcom and Cypress Wi-Fi chips, used in RPi family of devices aka 'Kr00k'. (bsc#1167162) - CVE-2021-33098: Fixed a potential denial of service in Intel(R) Ethernet ixgbe driver due to improper input validation.

(bsc#1193575) - CVE-2021-0920: Fixed a local privilege escalation due to an use after free bug in unix_gc. (bsc#1193731) - CVE-2021-45485: Fixed an information leak because of certain use of a hash table which use IPv6 source addresses. (bsc#1194094) - CVE-2021-45486: Fixed an information leak because the hash table is very small in net/ipv4/route.c. (bsc#1194087) - CVE-2021-28715: Fixed an issue where a guest could force Linux netback driver to hog large amounts of kernel memory by do not queueing unlimited number of packages. (bsc#1193442) - CVE-2021-28714: Fixed an issue where a guest could force Linux netback driver to hog large amounts of kernel memory by fixing rx queue stall detection. (bsc#1193442) - CVE-2021-28713: Fixed a rogue backends that could cause DoS of guests via high frequency events by hardening hvc_xen against event channel storms.

(bsc#1193440) - CVE-2021-43975: Fixed a flaw in hw_atl_utils_fw_rpc_wait that could allow an attacker (who can introduce a crafted device) to trigger an out-of-bounds write via a crafted length value. (bsc#1192845) - CVE-2021-43976: Fixed a flaw that could allow an attacker (who can connect a crafted USB device) to cause a denial of service.
