Summary:
The remote host is missing an update for the 'linux' Linux Distribution Package(s) announced via the USN-4163-1 advisory.

Detection Method:
Checks if a vulnerable Linux Distribution Package version is present on the target host.

Technical Details:
It was discovered that a race condition existed in the ARC EMAC ethernet driver for the Linux kernel, resulting in a use-after-free vulnerability. An attacker could use this to cause a denial of service (system crash). (CVE-2016-10906) It was discovered that a race condition existed in the Serial Attached SCSI (SAS) implementation in the Linux kernel when handling certain error conditions. A local attacker could use this to cause a denial of service (kernel deadlock). (CVE-2017-18232) It was discovered that the RSI 91x Wi-Fi driver in the Linux kernel did not did not handle detach operations correctly, leading to a use-after-free vulnerability. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-21008) The Marvell Wi-Fi device driver in the Linux kernel did not properly perform bounds checking, leading to a heap overflow. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14814, CVE-2019-14816) Matt Delco discovered that the KVM hypervisor implementation in the Linux kernel did not properly perform bounds checking when handling coalesced MMIO write operations. A local attacker with write access to /dev/kvm could use this to cause a denial of service (system crash). (CVE-2019-14821) Hui Peng and Mathias Payer discovered that the USB audio driver for the Linux kernel did not properly validate device meta data. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15117) Hui Peng and Mathias Payer discovered that the USB audio driver for the Linux kernel improperly performed recursion while handling device meta data. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15118) It was discovered that the Technisat DVB-S/S2 USB device driver in the Linux kernel contained a buffer overread. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2019-15505) Brad Spengler discovered that a Spectre mitigation was improperly implemented in the ptrace subsystem of the Linux kernel. A local attacker could possibly use this to expose sensitive information. (CVE-2019-15902)
