referenced in the SUSE-SU-2023:0147-1 advisory.

  - An issue was discovered in the Linux kernel through 5.16-rc6. lkdtm_ARRAY_BOUNDS in
    drivers/misc/lkdtm/bugs.c lacks check of the return value of kmalloc() and will cause the null pointer
    dereference. (CVE-2022-3104)

  - An issue was discovered in the Linux kernel through 5.16-rc6. uapi_finalize in
    drivers/infiniband/core/uverbs_uapi.c lacks check of kmalloc_array(). (CVE-2022-3105)

  - An issue was discovered in the Linux kernel through 5.16-rc6. ef100_update_stats in
    drivers/net/ethernet/sfc/ef100_nic.c lacks check of the return value of kmalloc(). (CVE-2022-3106)

  - An issue was discovered in the Linux kernel through 5.16-rc6. netvsc_get_ethtool_stats in
    drivers/net/hyperv/netvsc_drv.c lacks check of the return value of kvmalloc_array() and will cause the
    null pointer dereference. (CVE-2022-3107)

  - An issue was discovered in the Linux kernel through 5.16-rc6. kfd_parse_subtype_iolink in
    drivers/gpu/drm/amd/amdkfd/kfd_crat.c lacks check of the return value of kmemdup(). (CVE-2022-3108)

  - An issue was discovered in the Linux kernel through 5.16-rc6. free_charger_irq() in
    drivers/power/supply/wm8350_power.c lacks free of WM8350_IRQ_CHG_FAST_RDY, which is registered in
    wm8350_init_charger(). (CVE-2022-3111)

  - An issue was discovered in the Linux kernel through 5.16-rc6. amvdec_set_canvases in
    drivers/staging/media/meson/vdec/vdec_helpers.c lacks check of the return value of kzalloc() and will
    cause the null pointer dereference. (CVE-2022-3112)

  - An issue was discovered in the Linux kernel through 5.16-rc6. mtk_vcodec_fw_vpu_init in
    drivers/media/platform/mtk-vcodec/mtk_vcodec_fw_vpu.c lacks check of the return value of devm_kzalloc()
    and will cause the null pointer dereference. (CVE-2022-3113)

  - An issue was discovered in the Linux kernel through 5.16-rc6. malidp_crtc_reset in
    drivers/gpu/drm/arm/malidp_crtc.c lacks check of the return value of kzalloc() and will cause the null
    pointer dereference. (CVE-2022-3115)

  - A flaw was found in the KVM's AMD nested virtualization (SVM). A malicious L1 guest could purposely fail
    to intercept the shutdown of a cooperative nested guest (L2), possibly leading to a page fault and kernel
    panic in the host (L0). (CVE-2022-3344)

  - A vulnerability classified as critical was found in Linux Kernel. Affected by this vulnerability is the
    function l2cap_reassemble_sdu of the file net/bluetooth/l2cap_core.c of the component Bluetooth. The
    manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The associated
    identifier of this vulnerability is VDB-211087. (CVE-2022-3564)

  - A use-after-free vulnerability was found in __nfs42_ssc_open() in fs/nfs/nfs4file.c in the Linux kernel.
    This flaw allows an attacker to conduct a remote denial (CVE-2022-4379)

  - A flaw incorrect access control in the Linux kernel USB core subsystem was found in the way user attaches
    usb device. A local user could use this flaw to crash the system. (CVE-2022-4662)

  - An issue was discovered in the Linux kernel before 6.0.11. Missing offset validation in
    drivers/net/wireless/microchip/wilc1000/hif.c in the WILC1000 wireless driver can trigger an out-of-bounds
    read when parsing a Robust Security Network (RSN) information element from a Netlink packet.
