GIGABYTE Multiple Products Privilege Escalation Vulnerability
The GPCIDrv and GDrv low-level drivers in GIGABYTE App Center, AORUS Graphics Engine, XTREME Gaming Engine, and OC GURU expose functionality to read and write arbitrary physical memory. This could be leveraged by a local attacker to elevate privileges.
A remote attacker, without authentication, can achieve full data confidentiality loss, arbitrary modification of data, complete denial of service or system unavailability. CISA has confirmed use of this vulnerability in known ransomware campaigns — treat as high priority for remediation. Federal agencies are required to remediate by 2022-11-14 under CISA BOD 22-01.
This vulnerability affects GIGABYTE Multiple Products. 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). Exploitation requires remote network access, low attack complexity, no authentication required, and no user interaction required.
