"The openSUSE Leap 15.1 kernel was updated to receive various security
and bugfixes.

The following security bugs were fixed :

  - CVE-2020-12351: A type confusion while processing AMP
    packets could be used by physical close attackers to
    crash the kernel or potentially execute code was fixed
    (bsc#1177724).

  - CVE-2020-12352: A stack information leak when handling
    certain AMP packets could be used by physical close
    attackers to leak information from the kernel was fixed
    (bsc#1177725).

  - CVE-2020-25212: A TOCTOU mismatch in the NFS client code
    could be used by local attackers to corrupt memory or
    possibly have unspecified other impact because a size
    check is in fs/nfs/nfs4proc.c instead of
    fs/nfs/nfs4xdr.c, aka CID-b4487b935452 (bnc#1176381).

  - CVE-2020-25645: Traffic between two Geneve endpoints may
    be unencrypted when IPsec is configured to encrypt
    traffic for the specific UDP port used by the GENEVE
    tunnel allowing anyone between the two endpoints to read
    the traffic unencrypted. The main threat from this
    vulnerability is to data confidentiality (bnc#1177511).

The following non-security bugs were fixed :

  - 59c7c3caaaf8 ('nvme: fix possible hang when ns scanning
    fails during error recovery')

  - NFS: On fatal writeback errors, we need to call
    nfs_inode_remove_request() (bsc#1177340).

  - NFS: Revalidate the file mapping on all fatal writeback
    errors (bsc#1177340).

  - drm/sun4i: mixer: Extend regmap max_register
    (git-fixes).

  - ea43d9709f72 ('nvme: fix identify error status silent
    ignore')

  - i2c: meson: fix clock setting overwrite (git-fixes).

  - iommu/vt-d: Correctly calculate agaw in domain_init()
    (bsc#1176400).

  - mac80211: do not allow bigger VHT MPDUs than the
    hardware supports (git-fixes).

  - macsec: avoid use-after-free in macsec_handle_frame()
    (git-fixes).

  - mm: memcg: switch to css_tryget() in
    get_mem_cgroup_from_mm() (bsc#1177685).

  - mmc: core: do not set limits.discard_granularity as 0
    (git-fixes).

  - nvme-multipath: do not reset on unknown status
    (bsc#1174748).

  - nvme-rdma: Avoid double freeing of async event data
    (bsc#1174748).

  - nvme: Fix ctrl use-after-free during sysfs deletion
    (bsc#1174748).

  - nvme: Namepace identification descriptor list is
    optional (bsc#1174748).

    list quirk (bsc#1174748).

    ns (bsc#1174748).

  - nvme: make nvme_identify_ns propagate errors back
    (bsc#1174748).

  - nvme: make nvme_report_ns_ids propagate error back
    (bsc#1174748).

  - nvme: pass status to nvme_error_status (bsc#1174748).
