______________________________________________________________________________

   An update that solves 40 vulnerabilities and has 47 fixes
   is now available.

Description:

   The SUSE Linux Enterprise 12 SP4 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)


   The following security bugs were fixed:

   - CVE-2021-0941: In bpf_skb_change_head of filter.c, there is a possible
     out of bounds read 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#1192045).
   - CVE-2021-31916: An out-of-bounds (OOB) memory write flaw was found in
     list_devices in drivers/md/dm-ioctl.c in the Multi-device driver module
     in the Linux kernel A bound check failure allowed an attacker with
     special user (CAP_SYS_ADMIN) privilege to gain access to out-of-bounds
     memory leading to a system crash or a leak of internal kernel
     information. The highest threat from this vulnerability is to system
     availability (bnc#1192781).
   - CVE-2021-20322: Make the ipv4 and ipv6 ICMP exception caches less
     predictive to avoid information leaks about UDP ports in use.
     (bsc#1191790)
   - CVE-2021-34981: Fixed file refcounting in cmtp when cmtp_attach_device
     fails. (bsc#1191961)
   - 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-2021-3715: Fixed a use-after-free in route4_change() in
     net/sched/cls_route.c (bsc#1190349).
   - CVE-2021-3760: Fixed a use-after-free vulnerability with the
     ndev->rf_conn_info object (bsc#1190067).
   - CVE-2021-42739: The firewire subsystem had a buffer overflow related to
     drivers/media/firewire/firedtv-avc.c and
     drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandled
     bounds checking (bsc#1184673).
   - CVE-2021-3542: Fixed heap buffer overflow in firedtv driver
     (bsc#1186063).
   - 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).
   - 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-2021-37159: 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-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-2021-3752: Fixed a use after free vulnerability in the Linux
     kernel's bluetooth module. (bsc#1190023)
   - CVE-2021-40490: Fixed a race condition discovered in the ext4 subsystem
     that could leat to local priviledge escalation. (bnc#1190159)
   - CVE-2021-3744: Fixed a bug which could allows attackers to cause a
     denial of service. (bsc#1189884)
   - CVE-2021-3764: Fixed a bug which could allows attackers to cause a
     denial of service. (bsc#1190534)
   - CVE-2021-3772: Fixed a remote denial of service in the SCTP stack, if
     the attacker can spoof IP addresses and knows the IP-addresses and port
     numbers being used (bnc#1190351).
   - 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-2021-3640: Fixed a Use-After-Free vulnerability in function
     sco_sock_sendmsg() in the bluetooth stack (bsc#1188172).
   - CVE-2021-3653: Missing validation of the `int_ctl` VMCB field and allows
     a malicious L1 guest to enable AVIC support for the L2 guest.
     (bsc#1189399).
   - 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-2021-3679: 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).

     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

     (bnc#1189291).

     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-2021-37576: 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-2020-0429: In l2tp_session_delete and related functions of
     l2tp_core.c, there is possible memory corruption due to a use after
     free. This could lead to local escalation of privilege with System
     execution privileges needed. (bsc#1176724).
