Vulnerability identifier: #VU22755

Vulnerability risk: Low

CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2019-0155

CWE-ID: CWE-284

Exploitation vector: Local

Exploit availability: No

Vulnerable software:
Intel Graphics Driver for Linux
Hardware solutions / Drivers
Intel Graphics Driver for Windows
Client/Desktop applications / Virtualization software

Vendor: Intel

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to improper access restrictions in Intel GPU subsystem. A local unprivileged user can perform blitter manipulation manipulation and write data to arbitrary location in kernel memory. As a result a local authenticated user can execute arbitrary code on the system with superuser privileges.

This vulnerability affects the following Intel products:

- 6th, 7th, 8th and 9th Generation Intel(R) Core(TM) Processor Families

- Intel(R) Pentium(R) Processor J, N, Silver and Gold Series

- Intel(R) Celeron(R) Processor J, N, G3900 and G4900 Series

- Intel(R) Atom(R) Processor A and E3900 Series

- Intel(R) Xeon(R) Processor E3-1500 v5 and v6, E-2100 and E-2200 Processor Families

- Intel(R) Graphics Driver for Windows before 26.20.100.6813 (DCH) or 26.20.100.6812 and before 21.20.x.5077 (aka15.45.5077)

- i915 Linux Driver for Intel(R) Processor Graphics before versions 5.4-rc7, 5.3.11, 4.19.84, 4.14.154, 4.9.201, 4.4.201

Mitigation
Install updates from vendor's website.
