Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The SUSE Linux Enterprise 12 kernel was updated to 3.12.61 to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2017-16939: The XFRM dump policy implementation in     net/xfrm/xfrm_user.c in the Linux kernel allowed local     users to gain privileges or cause a denial of service     (use-after-free) via a crafted SO_RCVBUF setsockopt     system call in conjunction with XFRM_MSG_GETPOLICY     Netlink messages (bnc#1069702 1069708).

  - CVE-2017-1000405: The Linux Kernel had a problematic use     of pmd_mkdirty() in the touch_pmd() function inside the     THP implementation. touch_pmd() could be reached by     get_user_pages(). In such case, the pmd would become     dirty. This scenario breaks the new     can_follow_write_pmd()'s logic - pmd could become dirty     without going through a COW cycle. This bug was not as     severe as the original 'Dirty cow' because an ext4 file     (or any other regular file) could not be mapped using     THP. Nevertheless, it did allow us to overwrite     read-only huge pages. For example, the zero huge page     and sealed shmem files could be overwritten (since their     mapping could be populated using THP). Note that after     the first write page-fault to the zero page, it will be     replaced with a new fresh (and zeroed) thp (bnc#1069496     1070307).

  - CVE-2017-16649: The usbnet_generic_cdc_bind function in     drivers/net/usb/cdc_ether.c in the Linux kernel allowed     local users to cause a denial of service (divide-by-zero     error and system crash) or possibly have unspecified     other impact via a crafted USB device (bnc#1067085).

  - CVE-2014-0038: The compat_sys_recvmmsg function in     net/compat.c in the Linux kernel, when CONFIG_X86_X32 is     enabled, allowed local users to gain privileges via a     recvmmsg system call with a crafted timeout pointer     parameter (bnc#860993).

  - CVE-2017-16650: The qmi_wwan_bind function in     drivers/net/usb/qmi_wwan.c in the Linux kernel allowed     local users to cause a denial of service (divide-by-zero     error and system crash) or possibly have unspecified     other impact via a crafted USB device (bnc#1067086).

  - CVE-2017-16535: The usb_get_bos_descriptor function in     drivers/usb/core/config.c in the Linux kernel allowed     local users to cause a denial of service (out-of-bounds     read and system crash) or possibly have unspecified     other impact via a crafted USB device (bnc#1066700).

  - CVE-2017-15102: The tower_probe function in     drivers/usb/misc/legousbtower.c in the Linux kernel     allowed local users (who are physically proximate for     inserting a crafted USB device) to gain privileges by     leveraging a write-what-where condition that occurs     after a race condition and a NULL pointer dereference     (bnc#1066705).

  - CVE-2017-16531: drivers/usb/core/config.c in the Linux     kernel allowed local users to cause a denial of service     (out-of-bounds read and system crash) or possibly have     unspecified other impact via a crafted USB device,     related to the USB_DT_INTERFACE_ASSOCIATION descriptor     (bnc#1066671).

  - CVE-2017-12193: The     assoc_array_insert_into_terminal_node function in     lib/assoc_array.c in the Linux kernel mishandled node     splitting, which allowed local users to cause a denial     of service (NULL pointer dereference and panic) via a     crafted application, as demonstrated by the keyring key     type, and key addition and link creation operations     (bnc#1066192).

  - CVE-2017-16529: The snd_usb_create_streams function in     sound/usb/card.c in the Linux kernel allowed local users     to cause a denial of service (out-of-bounds read and     system crash) or possibly have unspecified other impact     via a crafted USB device (bnc#1066650).

  - CVE-2017-16525: The usb_serial_console_disconnect     function in drivers/usb/serial/console.c in the Linux     kernel allowed local users to cause a denial of service     (use-after-free and system crash) or possibly have     unspecified other impact via a crafted USB device,     related to disconnection and failed setup (bnc#1066618).

  - CVE-2017-16537: The imon_probe function in     drivers/media/rc/imon.c in the Linux kernel allowed     local users to cause a denial of service (NULL pointer     dereference and system crash) or possibly have     unspecified other impact via a crafted USB device     (bnc#1066573).

  - CVE-2017-16536: The cx231xx_usb_probe function in     drivers/media/usb/cx231xx/cx231xx-cards.c in the Linux     kernel allowed local users to cause a denial of service     (NULL pointer dereference and system crash) or possibly     have unspecified other impact via a crafted USB device     (bnc#1066606).

  - CVE-2017-16527: sound/usb/mixer.c in the Linux kernel     allowed local users to cause a denial of service     (snd_usb_mixer_interrupt use-after-free and system     crash) or possibly have unspecified other impact via a     crafted USB device (bnc#1066625).

  -2.6.38から4.14までのバージョンのLinuxカーネルでは、THPの実装内のtouch_pmd()関数でpmd_mkdirty()が問題のある方法で使用されています。touch_pmd()はget_user_pages()の影響を受ける可能性があります。そのような場合、pmdはダーティとなります。この状況では、新たなcan_follow_write_pmd()のロジックは破綻します-pmdはCOWサイクルを経ることなくダーティとなる可能性があります。このバグは、ext4ファイル（またはその他の通常のファイル）はTHPを使用してマッピングできないため、元のDirty Cowほど重大ではありません。とはいえ、読み取り専用のhuge pageが上書きされる可能性があります。たとえば、ゼロ埋めされたhuge pageやシールされたshmemファイルが上書きされる可能性があります（マッピングがTHPを使用して行われるため）。なお、最初にページフォルトをゼロページに書き込んだ後は、新規の（ゼロ埋めされた）THPに置き換わります。（CVE-2017-1000405）

  -4.13.8より前のLinuxカーネルのblock/bio.cのbio_map_user_iovおよびbio_unmap_user関数は、SCSI I/Oベクトルが同じページに属する小型の連続したバッファを持つ場合に、アンバランスな参照カウントを行います。
    bio_add_pc_page関数はこれらを1つにマージしますが、ページ参照は決してドロップされません。これにより、メモリ不足の状態により、メモリリークと、システムのロックアップ（SCSIディスクが仮想マシンに渡される場合、ゲストOSのユーザーによってホストOSに対して悪用可能）が発生します。（CVE-2017-12190）

  -4.13.6より前のLinuxカーネルのnet/packet/af_packet.cにより、ローカルユーザーが特別に細工されたシステムコールを介して権限を取得し、packet_fanoutデータ構造を誤って処理させる可能性があります。これは競合状態（fanout_addとpacket_do_bindを含む）が原因で、メモリ解放後使用（Use After Free）が発生するためです。これはCVE-2017-6346とは異なる脆弱性です。（CVE-2017-15649）

  -4.13.8より前のLinuxカーネルのsound/sound/mixer.cにより、ローカルユーザーが細工されたUSBデバイスを介してサービス拒否（snd_usb_mixer_interruptメモリ解放後使用（Use After Free）およびシステムクラッシュ）を引き起こしたり、詳細不明なその他の影響を与えたりする可能性があります。（CVE-2017-16527）
