Description: | Summary: The remote host is missing an update for the 'linux, linux-azure, linux-gcp, linux-gke-4.15, linux-hwe, linux-kvm, linux-oracle, linux-raspi2' package(s) announced via the USN-4115-1 advisory.
Vulnerability Insight: Hui Peng and Mathias Payer discovered that the Option USB High Speed driver in the Linux kernel did not properly validate metadata received from the device. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2018-19985)
Zhipeng Xie discovered that an infinite loop could be triggered in the CFS Linux kernel process scheduler. A local attacker could possibly use this to cause a denial of service. (CVE-2018-20784)
It was discovered that the Intel Wi-Fi device driver in the Linux kernel did not properly validate certain Tunneled Direct Link Setup (TDLS). A physically proximate attacker could use this to cause a denial of service (Wi-Fi disconnect). (CVE-2019-0136)
It was discovered that the Bluetooth UART implementation in the Linux kernel did not properly check for missing tty operations. A local attacker could use this to cause a denial of service. (CVE-2019-10207)
Amit Klein and Benny Pinkas discovered that the Linux kernel did not sufficiently randomize IP ID values generated for connectionless networking protocols. A remote attacker could use this to track particular Linux devices. (CVE-2019-10638)
Amit Klein and Benny Pinkas discovered that the location of kernel addresses could be exposed by the implementation of connection-less network protocols in the Linux kernel. A remote attacker could possibly use this to assist in the exploitation of another vulnerability in the Linux kernel. (CVE-2019-10639)
It was discovered that an integer overflow existed in the Linux kernel when reference counting pages, leading to potential use-after-free issues. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-11487)
Jann Horn discovered that a race condition existed in the Linux kernel when performing core dumps. A local attacker could use this to cause a denial of service (system crash) or expose sensitive information. (CVE-2019-11599)
It was discovered that a null pointer dereference vulnerability existed in the LSI Logic MegaRAID driver in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2019-11810)
It was discovered that the GTCO tablet input driver in the Linux kernel did not properly bounds check the initial HID report sent by the device. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-13631)
Praveen Pandey discovered that the Linux kernel did not properly validate sent signals in some situations on PowerPC systems with transactional memory disabled. A local attacker could use this to cause a denial of service. (CVE-2019-13648)
It was discovered that the floppy driver in the Linux kernel did not properly validate meta data, leading to a buffer overread. A local attacker could use this to cause a denial of service ... [Please see the references for more information on the vulnerabilities]
