The SUSE Linux Enterprise 15 SP3 kernel was updated - Unprivileged BPF has been disabled by default to reduce attack surface as too many security issues have happened in the past (jsc#SLE-22573) You can reenable via systemctl setting /proc/sys/kernel/unprivileged_bpf_disabled to 0. (kernel.unprivileged_bpf_disabled = 0) The following security bugs were fixed: - 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. (bnc#1194087). - CVE-2021-4001: Fixed a race condition when the EBPF map is frozen. (bsc#1192990) - 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-2021-28712: Fixed a rogue backends that could cause DoS of guests via high frequency events by hardening netfront against event channel storms. (bsc#1193440) - CVE-2021-28711: Fixed a rogue backends that could cause DoS of guests via high frequency events by hardening blkfront against event channel storms. (bsc#1193440) - CVE-2020-24504: Fixed an uncontrolled resource consumption in some Intel(R) Ethernet E810 Adapter drivers that may have allowed an authenticated user to potentially enable denial of service via local access. (bnc#1182404) - 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. (bnc#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. (bnc#1192847) - CVE-2021-4002: Added a missing TLB flush that could lead to leak or corruption of data in hugetlbfs. (bsc#1192946) - CVE-2020-27820: Fixed a vulnerability where a use-after-frees in nouveau's postclose() handler could happen if removing device.
