An update that solves six vulnerabilities and has seven fixes can now be
installed.

## Description:

The SUSE Linux Enterprise 12 SP5 Azure kernel was updated to receive various
security and bugfixes.

    (bsc#1203331).
  * CVE-2022-4129: Fixed a denial of service with the Layer 2 Tunneling Protocol
    (L2TP). A missing lock when clearing sk_user_data can lead to a race
    condition and NULL pointer dereference. (bsc#1205711)
  * CVE-2023-0597: Fixed lack of randomization of per-cpu entry area in x86/mm
    (bsc#1207845).
  * CVE-2023-1118: Fixed a use-after-free bugs caused by ene_tx_irqsim() in
    media/rc (bsc#1208837).
  * CVE-2023-23559: Fixed integer overflow in rndis_wlan that leads to a buffer
    overflow (bsc#1207051).
  * CVE-2023-26545: Fixed double free in net/mpls/af_mpls.c upon an allocation
    failure (bsc#1208700).

The following non-security bugs were fixed:

  * bonding: fix 802.3ad state sent to partner when unbinding slave (git-fixes).
  * do not sign the vanilla kernel (bsc#1209008).
  * icmp: do not fail on fragment reassembly time exceeded (git-fixes).
  * ipmi: fix initialization when workqueue allocation fails (git-fixes).
  * ipmi: msghandler: Make symbol 'remove_work_wq' static (git-fixes).
  * kabi fix for - SUNRPC: Fix priority queue fairness (git-fixes).
  * kabi fix for: NFS: Pass error information to the pgio error cleanup routine
    (git-fixes).
  * kabi/severities: add l2tp local symbols
  * kernel-module-subpackage: Fix expansion with -b parameter (bsc#1208179).
    When -b is specified the script is prefixed with KMP_NEEDS_MKINITRD=1 which
    sets the variable for a simple command. However, the script is no longer a
    simple command. Export the variable instead.
  * media: coda: Add check for dcoda_iram_alloc (git-fixes).
  * media: coda: Add check for kmalloc (git-fixes).
  * media: platform: ti: Add missing check for devm_regulator_get (git-fixes).
  * net: aquantia: fix RSS table and key sizes (git-fixes).
  * netfilter: ipvs: Fix inappropriate output of procfs (git-fixes).
  * netfilter: xt_connlimit: do not store address in the conn nodes (git-fixes).

    fixes).
  * nfs: Pass error information to the pgio error cleanup routine (git-fixes).
  * nfsd: fix handling of readdir in v4root vs. mount upcall timeout (git-
    fixes).
  * nfsd: fix race to check ls_layouts (git-fixes).
  * nfsd: under NFSv4.1, fix double svc_xprt_put on rpc_create failure (git-
    fixes).
  * ocfs2: Fix data corruption after failed write (bsc#1208542).
  * pNFS/filelayout: Fix coalescing test for single DS (git-fixes).
  * powerpc/eeh: Fix use-after-release of EEH driver (bsc#1065729).
  * powerpc/fscr: Enable interrupts earlier before calling get_user()
    (bsc#1065729).
  * powerpc/powernv: Fix build error in opal-imc.c when NUMA=n (bsc#1065729).
  * powerpc/powernv: IMC fix out of bounds memory access at shutdown
    (bsc#1065729).
  * scsi: qla2xxx: Add option to disable FC2 Target support (bsc#1198438
    bsc#1206103).
  * sunrpc: Fix priority queue fairness (git-fixes).
