   An update that solves 38 vulnerabilities and has 18 fixes
   is now available.

Description:



   The SUSE Linux Enterprise 12 SP3 LTSS 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-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-2020-12655: An issue was discovered in xfs_agf_verify in
     fs/xfs/libxfs/xfs_alloc.c. Attackers may trigger a sync of excessive
     duration via an XFS v5 image with crafted metadata, aka CID-d0c7feaf8767
     (bnc#1171217).
   - CVE-2021-43389: There was an array-index-out-of-bounds flaw in the
     detach_capi_ctr function in drivers/isdn/capi/kcapi.c (bnc#1191958).
   - CVE-2021-37159: hso_free_net_device in drivers/net/usb/hso.c called
     unregister_netdev without checking for the NETREG_REGISTERED state,
     leading to a use-after-free and a double free (bnc#1188601).
   - 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).
   - 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).
   - CVE-2017-17862: kernel/bpf/verifier.c in the Linux kernel ignores
     unreachable code, even though it would still be processed by JIT
     compilers. This behavior, also considered an improper branch-pruning
     logic issue, could possibly be used by local users for denial of service
     (bnc#1073928).
   - CVE-2017-17864: kernel/bpf/verifier.c in the Linux kernel mishandled
     states_equal comparisons between the pointer data type and the
     UNKNOWN_VALUE data type, which allowed local users to obtain potentially
     sensitive address information, aka a "pointer leak (bnc#1073928).
   - CVE-2021-20265: A flaw was found in the way memory resources were freed
     in the unix_stream_recvmsg function in the Linux kernel when a signal
     was pending. This flaw allowed an unprivileged local user to crash the
     system by exhausting available memory. The highest threat from this
     vulnerability is to system availability (bnc#1183089).
   - CVE-2021-3772: Fixed sctp vtag check in sctp_sf_ootb (bsc#1190351).
   - CVE-2021-3655: Missing size validations on inbound SCTP packets may have
     allowed the kernel to read uninitialized memory (bnc#1188563).
   - 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).
   - CVE-2021-3760: Fixed a use-after-free vulnerability with the
     ndev->rf_conn_info object (bsc#1190067).
   - 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).
   - CVE-2021-3542: Fixed heap buffer overflow in firedtv driver
     (bsc#1186063).
   - 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).
   - CVE-2020-14305: An out-of-bounds memory write flaw was found in how the
     Linux kernel’s Voice Over IP H.323 connection tracking
     functionality handled connections on ipv6 port 1720. This flaw allowed
     an unauthenticated remote user to crash the system, causing a denial of
     service. The highest threat from this vulnerability is to
     confidentiality, integrity, as well as system availability (bnc#1173346).
   - CVE-2021-3715: Fixed a use-after-free in route4_change() in
     net/sched/cls_route.c (bsc#1190349).
   - CVE-2021-3896: Fixed a array-index-out-bounds in detach_capi_ctr in
     drivers/isdn/capi/kcapi.c (bsc#1191958).
   - 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).
   - 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).
   - CVE-2021-3752: Fixed a use after free vulnerability in the Linux
     kernel's bluetooth module. (bsc#1190023)
   - 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)
   - CVE-2021-3640: Fixed a Use-After-Free vulnerability in function
     sco_sock_sendmsg() in the bluetooth stack (bsc#1188172).
   - 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-2021-3753: Fixed race out-of-bounds in virtual terminal handling
     (bsc#1190025).
   - CVE-2021-3732: Mounting overlayfs inside an unprivileged user namespace
     can reveal files (bsc#1189706).
   - 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 bnc#1189420).
   - CVE-2021-38198: arch/x86/kvm/mmu/paging_tmpl.h in the Linux kernel
     incorrectly computes the access permissions of a shadow page, leading to
     a missing guest protection page fault (bnc#1189262 bnc#1189278).
   - CVE-2021-38204: drivers/usb/host/max3421-hcd.c in the Linux kernel
     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-2021-3679: A lack of CPU resource in the Linux kernel tracing module
     functionality in versions prior to 5.14-rc3 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-2018-16882: A use-after-free issue was found in the way the Linux
     kernel's KVM hypervisor processed posted interrupts when nested(=1)
     virtualization is enabled. In nested_get_vmcs12_pages(), in case of an
     error while processing posted interrupt address, it unmaps the
     'pi_desc_page' without resetting 'pi_desc' descriptor address, which is
     later used in pi_test_and_clear_on(). A guest user/process could use
     this flaw to crash the host kernel resulting in DoS or potentially gain
     privileged access to a system. Kernel versions and are vulnerable
     (bnc#1119934).
   - 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).
   - 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#1177666 bnc#1181158).
   - CVE-2021-3659: Fixed a NULL pointer dereference in llsec_key_alloc() in
     net/mac802154/llsec.c (bsc#1188876).
   - CVE-2021-37576: arch/powerpc/kvm/book3s_rtas.c in the Linux kernel on
     the powerpc platform allowed KVM guest OS users to cause host OS memory
     corruption via rtas_args.nargs, aka CID-f62f3c20647e (bnc#1188838).
