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


The following security bugs were fixed:

- CVE-2022-0435: Fixed remote stack overflow in net/tipc module that validate domain record count on input (bsc#1195254).
- CVE-2021-3564: Fixed double-free memory corruption in the Linux kernel HCI device initialization subsystem that could have been used by attaching malicious HCI TTY Bluetooth devices. A local user could use this flaw to crash the system (bnc#1186207).
- CVE-2021-45095: Fixed refcount leak in pep_sock_accept in net/phonet/pep.c (bnc#1193867).
- CVE-2021-39657: Fixed out of bounds read due to a missing bounds check in ufshcd_eh_device_reset_handler of ufshcd.c. This could lead to local information disclosure with System execution privileges needed (bnc#1193864).
- CVE-2021-39648: Fixed possible disclosure of kernel heap memory due to a race condition in gadget_dev_desc_UDC_show of configfs.c. This could lead to local information disclosure with System execution privileges needed. User interaction is not needed for exploitation (bnc#1193861). 
- CVE-2021-44733: Fixed a use-after-free exists in drivers/tee/tee_shm.c in the TEE subsystem, that could have occured because of a race condition in tee_shm_get_from_id during an attempt to free a shared memory object (bnc#1193767).
- CVE-2022-0330: Fixed flush TLBs before releasing backing store (bsc#1194880).
- CVE-2022-0322: Fixed SCTP issue with account stream padding length for reconf chunk (bsc#1194985).
- CVE-2021-4197: Use cgroup open-time credentials for process migraton perm checks (bsc#1194302).
- CVE-2021-4202: Fixed NFC race condition by adding NCI_UNREG flag (bsc#1194529).
- CVE-2021-4083: Fixed a read-after-free memory flaw inside the garbage collection for Unix domain socket file handlers when users call close() and fget() simultaneouslyand can potentially trigger a race condition (bnc#1193727).
- CVE-2021-4149: Fixed btrfs unlock newly allocated extent buffer after error (bsc#1194001).
- CVE-2021-45486: Fixed an information leak because the hash table is very small in net/ipv4/route.c (bnc#1194087).
- CVE-2021-0920: Fixed a local privilege escalation due to an use after free bug in unix_gc (bsc#1193731).
- CVE-2021-28711: Fixed issue with xen/blkfront to harden blkfront against event channel storms (XSA-391) (bsc#1193440).
- CVE-2021-28712: Fixed issue with xen/netfront to harden netfront against event channel storms (XSA-391) (bsc#1193440).
- CVE-2021-28713: Fixed issue with xen/console to harden hvc_xen against event channel storms (XSA-391) (bsc#1193440).
- CVE-2021-28714: Fixed issue with xen/netback to handle rx queue stall detection (XSA-392) (bsc#1193442).
- CVE-2021-28715: Fixed issue with xen/netback to do not queue unlimited number of packages (XSA-392) (bsc#1193442).
- CVE-2018-25020: Fixed an overflow in the BPF subsystem due to a mishandling of a long jump over an instruction sequence where inner instructions require substantial expansions into multiple BPF instructions. This affects kernel/bpf/core.c and net/core/filter.c (bnc#1193575).
- CVE-2021-0935: Fixed possible out of bounds write in ip6_xmit of ip6_output.c due to a use after free. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation (bnc#1192032).
- CVE-2020-27820: Fixed a vulnerability where a use-after-frees in nouveau's postclose() handler could happen if removing device (bsc#1179599).
- CVE-2021-4002: Fixed incorrect TLBs flush in hugetlbfs after huge_pmd_unshare (bsc#1192946).
- CVE-2021-43975: hw_atl_utils_fw_rpc_wait in drivers/net/ethernet/aquantia/atlantic/hw_atl/hw_atl_utils.c allowed an attacker (who can introduce a crafted device) to trigger an out-of-bounds write via a crafted length value (bnc#1192845).
- CVE-2021-33098: Improper input validation in the Intel(R) Ethernet ixgbe driver for Linux before version 3.17.3 may have allowed an authenticated user to potentially enable denial of service via local access (bnc#1192877).
- CVE-2021-43976: mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allowed an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic) (bnc#1192847).
- CVE-2019-15126: Fixed a vulnerability in Broadcom and Cypress Wi-Fi chips, used in RPi family of devices aka "Kr00k" (bsc#1167162).
- CVE-2021-4159: Fixed kernel ptr leak vulnerability via BPF in coerce_reg_to_size (bsc#1194227).
