  - The Linux kernel is vulerable to a use-after-free flaw     when Transformation User configuration     interface(CONFIG_XFRM_USER) compile-time configuration     were enabled. This vulnerability occurs while closing a     xfrm netlink socket in xfrm_dump_policy_done. A     user/process could abuse this flaw to potentially     escalate their privileges on a system.(CVE-2017-16939)

  - The net/netfilter/nfnetlink_cthelper.c function in the     Linux kernel through 4.14.4 does not require the     CAP_NET_ADMIN capability for new, get, and del     operations. This allows local users to bypass intended     access restrictions because the nfnl_cthelper_list data     structure is shared across all net     namespaces.(CVE-2017-17448)

  - The __netlink_deliver_tap_skb function in     net/netlink/af_netlink.c in the Linux kernel, through     4.14.4, does not restrict observations of Netlink     messages to a single net namespace, when CONFIG_NLMON     is enabled. This allows local users to obtain sensitive     information by leveraging the CAP_NET_ADMIN capability     to sniff an nlmon interface for all Netlink activity on     the system.(CVE-2017-17449)

  - net/netfilter/xt_osf.c in the Linux kernel through     4.14.4 does not require the CAP_NET_ADMIN capability     for add_callback and remove_callback operations. This     allows local users to bypass intended access     restrictions because the xt_osf_fingers data structure     is shared across all network     namespaces.(CVE-2017-17450)

  - The usb_destroy_configuration() function, in     'drivers/usb/core/config.c' in the USB core subsystem,     in the Linux kernel through 4.14.5 does not consider     the maximum number of configurations and interfaces     before attempting to release resources. This allows     local users to cause a denial of service, due to     out-of-bounds write access, or possibly have     unspecified other impact via a crafted USB device. Due     to the nature of the flaw, privilege escalation cannot     be fully ruled out, although we believe it is     unlikely.(CVE-2017-17558)

  - The Salsa20 encryption algorithm in the Linux kernel,     before 4.14.8, does not correctly handle zero-length     inputs. This allows a local attacker the ability to use     the AF_ALG-based skcipher interface to cause a denial     of service (uninitialized-memory free and kernel crash)     or have an unspecified other impact by executing a     crafted sequence of system calls that use the     blkcipher_walk API. Both the generic implementation     (crypto/salsa20_generic.c) and x86 implementation     (arch/x86/crypto/salsa20_glue.c) of Salsa20 are     vulnerable.(CVE-2017-17805)

  - The HMAC implementation (crypto/hmac.c) in the Linux     kernel, before 4.14.8, does not validate that the     underlying cryptographic hash algorithm is unkeyed.
    This allows a local attacker, able to use the     AF_ALG-based hash interface     (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash     algorithm (CONFIG_CRYPTO_SHA3), to cause a kernel stack     buffer overflow by executing a crafted sequence of     system calls that encounter a missing SHA-3     initialization.(CVE-2017-17806)

  - The KEYS subsystem in the Linux kernel omitted an     access-control check when writing a key to the current     task's default keyring, allowing a local user to bypass     security checks to the keyring. This compromises the     validity of the keyring for those who rely on     it.(CVE-2017-17807)

  - A flaw was found in the Linux kernel's implementation     of i8042 serial ports. An attacker could cause a kernel     panic if they are able to add and remove devices as the     module is loaded.(CVE-2017-18079)

  - The Linux kernel, before version 4.14.3, is vulnerable     to a denial of service in     drivers/md/dm.c:dm_get_from_kobject() which can be     caused by local users leveraging a race condition with
    __dm_destroy() during creation and removal of DM     devices. Only privileged local users (with     CAP_SYS_ADMIN capability) can directly perform the     ioctl operations for dm device creation and removal and     this would typically be outside the direct control of     the unprivileged attacker.(CVE-2017-18203)

  - The madvise_willneed function in the Linux kernel     allows local users to cause a denial of service     (infinite loop) by triggering use of MADVISE_WILLNEED     for a DAX mapping.(CVE-2017-18208)

  - A flaw was found in the Linux kernel's implementation     of BPF in which systems can application can overflow a     32 bit refcount in both program and map refcount. This     refcount can wrap and end up a user after     free.(CVE-2016-4558i1/4%0

  - Interpretation conflict in     drivers/md/dm-snap-persistent.c in the Linux kernel     through 3.11.6 allows remote authenticated users to     obtain sensitive information or modify data via a     crafted mapping to a snapshot block     device.(CVE-2013-4299i1/4%0

  - The imon_probe function in drivers/media/rc/imon.c in     the Linux kernel through 4.13.11 allows 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.(CVE-2017-16537i1/4%0

  - A vulnerability in the handling of Transactional Memory     on powerpc systems was found. An unprivileged local     user can crash the kernel by starting a transaction,     suspending it, and then calling any of the exec() class     system calls.(CVE-2016-5828i1/4%0

  - A cross-boundary flaw was discovered in the Linux     kernel software raid driver. The driver accessed a     disabled bitmap where only the first byte of the buffer     was initialized to zero. This meant that the rest of     the request (up to 4095 bytes) was left and copied into     user space. An attacker could use this flaw to read     private information from user space that would not     otherwise have been accessible.(CVE-2015-5697i1/4%0

  - The parse_hid_report_descriptor function in     drivers/input/tablet/gtco.c in the Linux kernel before     4.13.11 allows 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.(CVE-2017-16643i1/4%0

  - drivers/net/usb/asix_devices.c in the Linux kernel     through 4.13.11 allows 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.(CVE-2017-16647i1/4%0

  - A flaw was found in the Linux kernel which could cause     a kernel panic when restoring machine specific     registers on the PowerPC platform. Incorrect     transactional memory state registers could     inadvertently change the call path on return from     userspace and cause the kernel to enter an unknown     state and crash.(CVE-2015-8845i1/4%0

  - fs/namespace.c in the Linux kernel through 3.16.1 does     not properly restrict clearing MNT_NODEV, MNT_NOSUID,     and MNT_NOEXEC and changing MNT_ATIME_MASK during a     remount of a bind mount, which allows local users to     gain privileges, interfere with backups and auditing on     systems that had atime enabled, or cause a denial of     service (excessive filesystem updating) on systems that     had atime disabled via a 'mount -o remount' command     within a user namespace.(CVE-2014-5207i1/4%0

  - The NFS2/3 RPC client could send long arguments to the     NFS server. These encoded arguments are stored in an     array of memory pages, and accessed using pointer     variables. Arbitrarily long arguments could make these     pointers point outside the array and cause an     out-of-bounds memory access. A remote user or program     could use this flaw to crash the kernel, resulting in     denial of service.(CVE-2017-7645i1/4%0

  - The time subsystem in the Linux kernel, when     CONFIG_TIMER_STATS is enabled, allows local users to     discover real PID values (as distinguished from PID     values inside a PID namespace) by reading the     /proc/timer_list file, related to the print_timer     function in kernel/time/timer_list.c and the
    __timer_stats_timer_set_start_info function in     kernel/time/timer.c.(CVE-2017-5967i1/4%0

  - A vulnerability was found in the Linux kernel where the     keyctl_set_reqkey_keyring() function leaks the thread     keyring. This allows an unprivileged local user to     exhaust kernel memory and thus cause a     DoS.(CVE-2017-7472i1/4%0

  - A flaw was found that can be triggered in     keyring_search_iterator in keyring.c if type-i1/4zmatch     is NULL. A local user could use this flaw to crash the     system or, potentially, escalate their     privileges.(CVE-2017-2647i1/4%0

  - The make_response function in     drivers/block/xen-blkback/blkback.c in the Linux kernel     before 4.11.8 allows guest OS users to obtain sensitive     information from host OS (or other guest OS) kernel     memory by leveraging the copying of uninitialized     padding fields in Xen block-interface response     structures, aka XSA-216.(CVE-2017-10911i1/4%0

  - Stack-based buffer overflow in the SET_WPS_IE IOCTL     implementation in wlan_hdd_hostapd.c in the WLAN (aka     Wi-Fi) driver for the Linux kernel 3.x and 4.x, as used     in Qualcomm Innovation Center (QuIC) Android     contributions for MSM devices and other products,     allows attackers to gain privileges via a crafted     application that uses a long WPS IE     element.(CVE-2015-0570i1/4%0

  - The net_ctl_permissions function in net/sysctl_net.c in     the Linux kernel before 3.11.5 does not properly     determine uid and gid values, which allows local users     to bypass intended /proc/sys/net restrictions via a     crafted application.(CVE-2013-4270i1/4%0

A vulnerability was found in the Linux kernel when peeling off an association to the socket in another network namespace. All transports in this association are not to be rehashed and keep using the old key in hashtable, thus removing transports from hashtable when closing the socket, all transports are being freed. Later on a use-after-free issue could be caused when looking up an association and dereferencing the transports. (CVE-2017-15115)

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

CVE-2016-10208

Sergej Schumilo and Ralf Spenneberg discovered that a crafted ext4 filesystem could trigger memory corruption when it is mounted. A user that can provide a device or filesystem image to be mounted could use this for denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-8824

Mohamed Ghannam discovered that the DCCP implementation did not correctly manage resources when a socket is disconnected and reconnected, potentially leading to a use-after-free. A local user could use this for denial of service (crash or data corruption) or possibly for privilege escalation. On systems that do not already have the dccp module loaded, this can be mitigated by disabling it: echo >> /etc/modprobe.d/disable-dccp.conf install dccp false

CVE-2017-8831

Pengfei Wang discovered that the saa7164 video capture driver re-reads data from a PCI device after validating it. A physically present user able to attach a specially designed PCI device could use this for privilege escalation.

CVE-2017-12190

Vitaly Mayatskikh discovered that the block layer did not correctly count page references for raw I/O from user-space. This can be exploited by a guest VM with access to a host SCSI device for denial of service (memory exhaustion) or potentially for privilege escalation.

CVE-2017-13080

A vulnerability was found in the WPA2 protocol that could lead to reinstallation of the same Group Temporal Key (GTK), which substantially reduces the security of wifi encryption. This is one of the issues collectively known as 'KRACK'.

Updates to GTKs are usually handled by the wpa package, where this issue was already fixed (DLA-1150-1). However, some wifi devices can remain active and update GTKs autonomously while the system is suspended. The kernel must also check for and ignore key reinstallation.

CVE-2017-14051

'shqking' reported that the qla2xxx SCSI host driver did not correctly validate I/O to the 'optrom' sysfs attribute of the devices it creates. This is unlikely to have any security impact.

CVE-2017-15115

Vladis Dronov reported that the SCTP implementation did not correctly handle 'peel-off' of an association to another net namespace. This leads to a use-after-free, which a local user can exploit for denial of service (crash or data corruption) or possibly for privilege escalation. On systems that do not already have the sctp module loaded, this can be mitigated by disabling it: echo >> /etc/modprobe.d/disable-sctp.conf install sctp false

CVE-2017-15265

Michael23 Yu reported a race condition in the ALSA sequencer subsystem involving creation and deletion of ports, which could lead to a use-after-free. A local user with access to an ALSA sequencer device can use this for denial of service (crash or data loss) or possibly for privilege escalation.

CVE-2017-15299

Eric Biggers discovered that the KEYS subsystem did not correctly handle update of an uninstantiated key, leading to a null dereference.
A local user can use this for denial of service (crash).

CVE-2017-15649

'nixioaming' reported a race condition in the packet socket (AF_PACKET) implementation involving rebinding to a fanout group, which could lead to a use-after-free. A local user with the CAP_NET_RAW capability can use this for denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-15868

Al Viro found that the Bluebooth Network Encapsulation Protocol (BNEP) implementation did not validate the type of the second socket passed to the BNEPCONNADD ioctl(), which could lead to memory corruption. A local user with the CAP_NET_ADMIN capability can use this for denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-16525

Andrey Konovalov reported that the USB serial console implementation did not correctly handle disconnection of unusual serial devices, leading to a use-after-free. A similar issue was found in the case where setup of a serial console fails. A physically present user with a specially designed USB device can use this to cause a denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-16527

Andrey Konovalov reported that the USB sound mixer driver did not correctly cancel I/O in case it failed to probe a device, which could lead to a use-after-free. A physically present user with a specially designed USB device can use this to cause a denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-16529

Andrey Konovalov reported that the USB sound driver did not fully validate descriptor lengths, which could lead to a buffer over-read. A physically present user with a specially designed USB device may be able to use this to cause a denial of service (crash).

CVE-2017-16531

Andrey Konovalov reported that the USB core did not validate IAD lengths, which could lead to a buffer over-read. A physically present user with a specially designed USB device may be able to use this to cause a denial of service (crash).

CVE-2017-16532

Andrey Konovalov reported that the USB test driver did not correctly handle devices with specific combinations of endpoints. A physically present user with a specially designed USB device can use this to cause a denial of service (crash).

CVE-2017-16533

Andrey Konovalov reported that the USB HID driver did not fully validate descriptor lengths, which could lead to a buffer over-read. A physically present user with a specially designed USB device may be able to use this to cause a denial of service (crash).

CVE-2017-16535

Andrey Konovalov reported that the USB core did not validate BOS descriptor lengths, which could lead to a buffer over-read. A physically present user with a specially designed USB device may be able to use this to cause a denial of service (crash).

CVE-2017-16536
