The remote openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:1477-1 advisory.

    The openSUSE Leap 15.2 kernel was updated to receive various security and bugfixes.

    The following security bugs were fixed:

    - CVE-2018-13405: The inode_init_owner function in fs/inode.c 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-2021-33033: The Linux kernel had 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#1188876).
    - 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-2021-3655: Missing size validations on inbound SCTP packets may have allowed the kernel to read     uninitialized memory (bnc#1188563 bnc#1192267).
    - 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-2021-3772: Invalid chunks may be used to remotely remove existing associations (bsc#1190351).
    - CVE-2021-3896: Fixed a array-index-out-bounds in detach_capi_ctr in drivers/isdn/capi/kcapi.c     (bsc#1191958).
    - CVE-2021-41864: prealloc_elems_and_freelist in kernel/bpf/stackmap.c allowed unprivileged users to     trigger an eBPF multiplication integer overflow with a resultant out-of-bounds write (bnc#1191317).
    - CVE-2021-42008: The decode_data function in drivers/net/hamradio/6pack.c had 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-2021-42252: An issue was discovered in aspeed_lpc_ctrl_mmap in drivers/soc/aspeed/aspeed-lpc-ctrl.c     where local attackers were 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).
    - 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 (bnc#1184673     bnc#1192036).
    - 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-2021-43056: It allowed a malicious KVM guest to crash the host, when the host is running on Power8,     due to an arch/powerpc/kvm/book3s_hv_rmhandlers.S implementation bug in the handling of the SRR1 register     values (bnc#1192107).
