The GPCIDrv and GDrv low-level drivers in GIGABYTE APP Center v1.05.21 and earlier, AORUS GRAPHICS ENGINE before 1.57, XTREME GAMING ENGINE before 1.26, and OC GURU II v2.08 expose functionality to read and write arbitrary physical memory. This could be leveraged by a local attacker to elevate privileges.

The version of GIGABYTE OC GURU II installed on the remote host is 2.08. It is, therefore, affected by multiple vulnerabilities as referenced in GIGABYTE security advisory 1801:

    - The GDrv low-level driver in GIGABYTE APP Center v1.05.21 and earlier, AORUS GRAPHICS ENGINE before 1.57, XTREME       GAMING ENGINE before 1.26, and OC GURU II v2.08 exposes ring0 memcpy-like functionality that could allow a local       attacker to take complete control of the affected system. (CVE-2018-19320)

    - The GPCIDrv and GDrv low-level drivers in GIGABYTE APP Center v1.05.21 and earlier, AORUS GRAPHICS ENGINE before       1.57, XTREME GAMING ENGINE before 1.26, and OC GURU II v2.08 expose functionality to read and write arbitrary       physical memory. This could be leveraged by a local attacker to elevate privileges. (CVE-2018-19321)

    - The GPCIDrv and GDrv low-level drivers in GIGABYTE APP Center v1.05.21 and earlier, AORUS GRAPHICS ENGINE before       1.57, XTREME GAMING ENGINE before 1.26, and OC GURU II v2.08 expose functionality to read/write data from/to IO       ports. This could be leveraged in a number of ways to ultimately run code with elevated privileges.
      (CVE-2018-19322)

    - The GDrv low-level driver in GIGABYTE APP Center v1.05.21 and earlier, AORUS GRAPHICS ENGINE before 1.57, XTREME       GAMING ENGINE before 1.26, and OC GURU II v2.08 exposes functionality to read and write Machine Specific Registers       (MSRs). (CVE-2018-19323)

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

The version of GIGABYTE AORUS GRAPHICS ENGINE installed on the remote host is prior to 1.57. It is, therefore, affected by multiple vulnerabilities as referenced in GIGABYTE security advisory 1801:

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

The version of GIGABYTE APP Center installed on the remote host is prior to 19.4.22.1. It is, therefore, affected by multiple vulnerabilities as referenced in GIGABYTE security advisory 1801:

    - The GDrv low-level driver in GIGABYTE APP Center v1.05.21 and earlier, AORUS GRAPHICS ENGINE before 1.57, XTREME       GAMING ENGINE before 1.26, and OC GURU II v2.08 exposes ring0 memcpy-like functionality that could allow a local       attacker to take complete control of the affected system.

    - An issue was discovered in gdrv.sys in Gigabyte APP Center before 19.0227.1. The vulnerable driver exposes a wrmsr       instruction via IOCTL 0xC3502580 and does not properly filter the target Model Specific Register (MSR). Allowing       arbitrary MSR writes can lead to Ring-0 code execution and escalation of privileges. (CVE-2019-7630)

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

The version of GIGABYTE XTREME GAMING ENGINE installed on the remote host is prior to 1.26. It is, therefore, affected by multiple vulnerabilities as referenced in GIGABYTE security advisory 1801:
