kernel: Out-of-bounds read in usbip/stub_rx.c:get_pipe() allows attackers to cause a denial of service via crafted USB over IP packet

The "get_pipe()" function (drivers/usb/usbip/stub_rx.c) in the Linux Kernel before version 4.14.8, 4.9.71, and 4.4.114 allows attackers to cause a denial of service (out-of-bounds read) via a specially crafted USB over IP packet.

kernel: vhci_cd driver in usbip/vhci_sysfs.c:port_show_vhci() discloses kernel memory addresses to local attackers

The vhci_hcd driver in the Linux Kernel before version 4.14.8 and 4.4.114 allows allows local attackers to disclose kernel memory addresses. Successful exploitation requires that a USB device is attached over IP.

kernel: net: double-free and memory corruption in get_net_ns_by_id()

A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before 4.14.11. The function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely.

kernel: Out of bound access in hugetlb_mcopy_atomic_pte function in mm/hugetlb.c

A flaw was found in the hugetlb_mcopy_atomic_pte function in mm/hugetlb.c in the Linux kernel before 4.13.12. A lack of size check could cause a denial of service (BUG).

kernel: Improper error handling of VM_SHARED hugetlbfs mapping in mm/hugetlb.c

A flaw was found in the hugetlb_mcopy_atomic_pte function in mm/hugetlb.c in the Linux kernel before 4.13. A superfluous implicit page unlock for VM_SHARED hugetlbfs mapping could trigger a local denial of service (BUG).

kernel: Use-after-free in userfaultfd_event_wait_completion function in userfaultfd.c

A use-after-free flaw was found in fs/userfaultfd.c in the Linux kernel before 4.13.6. The issue is related to the handling of fork failure when dealing with event messages. Failure to fork correctly can lead to a situation where a fork event will be removed from an already freed list of events with userfaultfd_ctx_put().

kernel: security: The built-in keyrings for security tokens can be joined as a session and then modified by the root user

It was discovered in the Linux kernel before 4.11-rc8 that root can gain direct access to an internal keyring, such as '.dns_resolver' in RHEL-7 or '.builtin_trusted_keys' upstream, by joining it as its session keyring. This allows root to bypass module signature verification by adding a new public key of its own devising to the keyring.

Cross-site scripting (XSS) vulnerability in Sophos PureMessage for UNIX before 6.3.2 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

chromium-browser: various fixes from internal audits

browser/extensions/api/dial/dial_registry.cc in Google Chrome before 54.0.2840.98 on macOS, before 54.0.2840.99 on Windows, and before 54.0.2840.100 on Linux neglects to copy a device ID before an erase() call, which causes the erase operation to access data that that erase operation will destroy.

kernel: out of bounds write in ad5755_parse_dt in drivers/iio/dac/ad5755.c

An issue was discovered in drivers/iio/dac/ad5755.c in the Linux kernel before 4.8.6. There is an out of bounds write in the function ad5755_parse_dt.
