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

The following security bugs were fixed:

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)

- CVE-2018-3639: Fixed a speculative execution that may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. (bsc#1087082)
- CVE-2021-20320: Fix a bug that allows a local attacker with special user privilege can circumvent the verifier and may lead to a confidentiality problem. (bsc#1190601)
- CVE-2021-0941: Fixed A missing sanity check to the current MTU check that may allow a local attacker with special user privilege to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. (bnc#1192045)
- CVE-2021-31916: Fixed a bound check failure that could allows an attacker with special user (CAP_SYS_ADMIN) privilege to gain access to out-of-bounds memory leading to a system crash, a leak of internal kernel information, or a privilege escalation problem. (bnc#1192781)
- CVE-2021-20322: Fixed a bug that provides to an attacker the ability to quickly scan open UDP ports. (bsc#1191790)
- CVE-2021-3772: Fixed an issue that would allow a blind attacker may be able to kill an existing SCTP association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and the attacker can send packets with spoofed IP addresses. (bsc#1190351)
- CVE-2021-34981: Fixed an issue that allows an attacker with a local account to escalate privileges when CAPI (ISDN) hardware connection fails. (bsc#1191961)
- CVE-2018-9517: Fixed possible memory corruption due to a use after free in pppol2tp_connect (bsc#1108488).
- CVE-2019-3874: Fixed possible denial of service attack via SCTP socket buffer used by a userspace applications (bnc#1129898).
- CVE-2019-3900: Fixed an infinite loop issue while handling incoming packets in handle_rx() (bnc#1133374).
- CVE-2020-12770: Fixed sg_remove_request call in a certain failure cases (bsc#1171420).
- CVE-2020-3702: Fixed a bug which could be triggered with specifically timed and handcrafted traffic and cause internal errors in a WLAN device that lead to improper layer 2 Wi-Fi encryption with a consequent possibility of information disclosure. (bnc#1191193)
- CVE-2021-22543: Fixed improper handling of VM_IO|VM_PFNMAP vmas in KVM, which could bypass RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allowed users with the ability to start and control a VM to read/write random pages of memory and can result in local privilege escalation (bsc#1186482).
- CVE-2021-33033: Fixed a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c because the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled (bsc#1186109).
- CVE-2021-34556: Fixed side-channel attack via a Speculative Store Bypass via unprivileged BPF program that could have obtain sensitive information from kernel memory (bsc#1188983).
- CVE-2021-35477: Fixed BPF stack frame pointer which could have been abused to disclose content of arbitrary kernel memory (bsc#1188985).

- CVE-2021-3655: Fixed a missing size validations on inbound SCTP packets, which may have allowed the kernel to read uninitialized memory (bsc#1188563).
- CVE-2021-3656: Missing validation of the the `virt_ext` VMCB field and allows a malicious L1 guest to disable both VMLOAD/VMSAVE intercepts and VLS for the L2 guest (bsc#1189400).
- CVE-2021-3659: Fixed a NULL pointer dereference in llsec_key_alloc() in net/mac802154/llsec.c (bsc#1188876).
- CVE-2021-3679: A lack of CPU resource in tracing module functionality was found in the way user uses trace ring buffer in a specific way. Only privileged local users (with CAP_SYS_ADMIN capability) could use this flaw to starve the resources causing denial of service (bnc#1189057).
- CVE-2021-37159: Fixed use-after-free and a double free inside hso_free_net_device in drivers/net/usb/hso.c when unregister_netdev is called without checking for the NETREG_REGISTERED state (bnc#1188601).
- CVE-2021-3732: Mounting overlayfs inside an unprivileged user namespace can reveal files (bsc#1189706).
- CVE-2021-3744: Fixed a bug which could allows attackers to cause a denial of service. (bsc#1189884)
- CVE-2021-3752: Fixed a use after free vulnerability in the Linux kernel's bluetooth module. (bsc#1190023)
- CVE-2021-3753: Fixed race out-of-bounds in virtual terminal handling (bsc#1190025).
- CVE-2021-37576: Fixed an issue on the powerpc platform, where a KVM guest OS user could cause host OS memory corruption via rtas_args.nargs (bsc#1188838).
- CVE-2021-3760: Fixed a use-after-free vulnerability with the ndev->rf_conn_info object (bsc#1190067).
- CVE-2021-3764: Fixed a bug which could allows attackers to cause a denial of service. (bsc#1190534)
- CVE-2021-38160: Data corruption or loss could be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size in drivers/char/virtio_console.c (bsc#1190117)
- CVE-2021-38198: arch/x86/kvm/mmu/paging_tmpl.h incorrectly computes the access permissions of a shadow page, leading to a missing guest protection page fault (bnc#1189262).
- CVE-2021-38204: drivers/usb/host/max3421-hcd.c allowed physically proximate attackers to cause a denial of service (use-after-free and panic) by removing a MAX-3421 USB device in certain situations (bnc#1189291).
- CVE-2021-40490: Fixed a race condition discovered in the ext4 subsystem that could leat to local priviledge escalation. (bnc#1190159)
- CVE-2021-41864: Fixed prealloc_elems_and_freelist that allowed unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds write (bnc#1191317).
- CVE-2021-42008: Fixed a slab out-of-bounds write in the decode_data function in drivers/net/hamradio/6pack.c. Input from a process that had the CAP_NET_ADMIN capability could have lead to root access (bsc#1191315).
- CVE-2021-42252: Fixed an issue inside aspeed_lpc_ctrl_mmap that could have allowed local attackers to access the Aspeed LPC control interface to overwrite memory in the kernel and potentially execute privileges (bnc#1190479).
