An update that solves 43 vulnerabilities, contains one feature and has 26 fixes
is now available.

Description:

The SUSE Linux Enterprise 15 SP1 LTSS kernel was updated to receive various
security and bugfixes.
The following security bugs were fixed:

  o 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)

  o 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).
  o 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).
  o CVE-2021-20322: Make the ipv4 and ipv6 ICMP exception caches less
    predictive to avoid information leaks about UDP ports in use. (bsc#1191790)
  o CVE-2021-34981: Fixed file refcounting in cmtp when cmtp_attach_device
    fails (bsc#1191961).
  o CVE-2021-37159: hso_free_net_device in drivers/net/usb/hso.c in the Linux
    kernel calls unregister_netdev without checking for the NETREG_REGISTERED
    state, leading to a use-after-free and a double free (bnc#1188601).
  o CVE-2021-3772: Fixed sctp vtag check in sctp_sf_ootb (bsc#1190351).
  o CVE-2021-3655: Missing size validations on inbound SCTP packets may have
    allowed the kernel to read uninitialized memory (bnc#1188563).
  o CVE-2021-33033: The Linux kernel has 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, aka CID-ad5d07f4a9cd. This leads to writing an
    arbitrary value (bnc#1186109 bnc#1186390 bnc#1188876).
  o CVE-2021-3760: Fixed a use-after-free vulnerability with the ndev->
    rf_conn_info object (bsc#1190067).
  o CVE-2021-42739: The firewire subsystem in the Linux kernel has 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 (bnc#
    1184673).
  o CVE-2021-3542: Fixed heap buffer overflow in firedtv driver (bsc#1186063).
  o CVE-2018-13405: The inode_init_owner function in fs/inode.c in the Linux
    kernel allowed local users to create files with an unintended group
    ownership, in a scenario where a directory is SGID to a certain group and
    is writable by a user who is not a member of that group. Here, the
    non-member can trigger creation of a plain file whose group ownership is
    that group. The intended behavior was that the non-member can trigger
    creation of a directory (but not a plain file) whose group ownership is
    that group. The non-member can escalate privileges by making the plain file
    executable and SGID (bnc#1100416 bnc#1129735).
  o CVE-2021-3715: Fixed a use-after-free in route4_change() in net/sched/
    cls_route.c (bsc#1190349).
  o CVE-2021-34556: An unprivileged BPF program can obtain sensitive
    information from kernel memory via a Speculative Store Bypass side-channel
    attack because the protection mechanism neglects the possibility of
    uninitialized memory locations on the BPF stack (bnc#1188983).
  o CVE-2021-35477: An unprivileged BPF program can obtain sensitive
    information from kernel memory via a Speculative Store Bypass side-channel
    attack because a certain preempting store operation did not necessarily
    occur before a store operation that has an attacker-controlled value (bnc#
    1188985).
  o CVE-2021-42252: An issue was discovered in aspeed_lpc_ctrl_mmap in drivers/
    soc/aspeed/aspeed-lpc-ctrl.c in the Linux kernel Local attackers able to
    access the Aspeed LPC control interface could overwrite memory in the
    kernel and potentially execute privileges, aka CID-b49a0e69a7b1. This
    occurs because a certain comparison uses values that are not memory sizes
    (bnc#1190479).
  o CVE-2021-41864: prealloc_elems_and_freelist in kernel/bpf/stackmap.c in the
    Linux kernel allowed unprivileged users to trigger an eBPF multiplication
    integer overflow with a resultant out-of-bounds write (bnc#1191317).
  o CVE-2021-42008: The decode_data function in drivers/net/hamradio/6pack.c in
    the Linux kernel has a slab out-of-bounds write. Input from a process that
    has the CAP_NET_ADMIN capability can lead to root access (bnc#1191315).
  o CVE-2021-3759: Unaccounted ipc objects could have lead to breaking memcg
    limits and DoS attacks (bsc#1190115).
  o CVE-2020-3702: Specifically timed and handcrafted traffic can cause
    internal errors in a WLAN device that lead to improper layer 2 Wi-Fi
    encryption with a consequent possibility of information disclosure over the
    air for a discrete set of traffic (bnc#1191193).
  o CVE-2021-3752: Fixed a use after free vulnerability in the bluetooth
    module. (bsc#1190023)
  o CVE-2021-40490: A race condition was discovered in
    ext4_write_inline_data_end in fs/ext4/inline.c in the ext4 subsystem in the
    Linux kernel (bnc#1190159 bnc#1192775)
  o CVE-2021-3744: Fixed a bug which could allows attackers to cause a denial
    of service. (bsc#1189884)
  o CVE-2021-3764: Fixed a bug which could allows attackers to cause a denial
    of service. (bsc#1190534)
  o CVE-2020-12770: An issue was discovered in the Linux kernel sg_write lacks
    an sg_remove_request call in a certain failure case, aka CID-83c6f2390040
    (bnc#1171420).
  o CVE-2021-3640: Fixed a Use-After-Free vulnerability in function
    sco_sock_sendmsg() in the bluetooth stack (bsc#1188172).
  o CVE-2019-3900: An infinite loop issue was found in the vhost_net kernel
    module, while handling incoming packets in handle_rx(). It could occur if
    one end sends packets faster than the other end can process them. A guest
    user, maybe remote one, could use this flaw to stall the vhost_net kernel
    thread, resulting in a DoS scenario (bnc#1133374).
  o CVE-2019-3874: The SCTP socket buffer used by a userspace application is
    not accounted by the cgroups subsystem. An attacker can use this flaw to
    cause a denial of service attack. (bnc#1129898).
  o CVE-2018-9517: In pppol2tp_connect, there is possible memory corruption 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#1108488).
  o 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)
  o CVE-2021-3753: Fixed race out-of-bounds in virtual terminal handling (bsc#
    1190025).
  o CVE-2021-3732: Mounting overlayfs inside an unprivileged user namespace can
    reveal files (bsc#1189706).
  o CVE-2021-3653: A flaw was found in the KVM's AMD code for supporting SVM
    nested virtualization. The flaw occurs when processing the VMCB (virtual
    machine control block) provided by the L1 guest to spawn/handle a nested
    guest (L2). Due to improper validation of the "int_ctl" field, this issue
    could allow a malicious L1 to enable AVIC support (Advanced Virtual
    Interrupt Controller) for the L2 guest. As a result, the L2 guest would be
    allowed to read/write physical pages of the host, resulting in a crash of
    the entire system, leak of sensitive data or potential guest-to-host
    escape. This flaw affects Linux kernel versions prior to 5.14-rc7 (bnc#
    1189399).
  o 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).
  o 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).
  o CVE-2021-3679: A lack of CPU resource in the 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).
  o CVE-2020-4788: IBM Power9 (AIX 7.1, 7.2, and VIOS 3.1) processors could
    allow a local user to obtain sensitive information from the data in the L1
    cache under extenuating circumstances. IBM X-Force ID: 189296 (bnc#0 bnc#
    1177666 bnc#1181158).
  o CVE-2021-3659: Fixed a NULL pointer dereference in llsec_key_alloc() in net
    /mac802154/llsec.c (bsc#1188876).
  o 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. User interaction is not needed for exploitation (bnc#1176724).
  o CVE-2021-37576: arch/powerpc/kvm/book3s_rtas.c on the powerpc platform
    allowed KVM guest OS users to cause host OS memory corruption via
    rtas_args.nargs, aka CID-f62f3c20647e (bnc#1188838 bnc#1190276).
  o CVE-2021-22543: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in
    KVM can 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 (bnc#1186482 bnc#1190276).
  o CVE-2021-33909: fs/seq_file.c did not properly restrict seq buffer
    allocations, leading to an integer overflow, an Out-of-bounds Write, and
    escalation to root by an unprivileged user, aka CID-8cae8cd89f05 (bnc#
    1188062 bnc#1188063).

______________________________________________________________________________

An update that solves four vulnerabilities, contains one feature and has 11
fixes is now available.

Description:

The SUSE Linux Enterprise 12 SP5 kernel was updated to receive various security
and bugfixes.
The following security bugs were fixed:

  o 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)

  o 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).
  o 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).
  o CVE-2021-20322: Make the ipv4 and ipv6 ICMP exception caches less
    predictive to avoid information leaks about UDP ports in use. (bsc#1191790)
  o CVE-2021-34981: Fixed file refcounting in cmtp when cmtp_attach_device
    fails. (bsc#1191961)


The following non-security bugs were fixed:

  o arm64: pgtable: make __pte_to_phys/__phys_to_pte_val inline functions
    (git-fixes).
  o arm64/sve: Use correct size when reinitialising SVE state (git-fixes).
