CVE-2018-12219

Vulnerability

An insufficient input validation vulnerability exists in the Kernel Mode Driver of Intel(R) Graphics Driver for Windows before versions 10.18.x.5059 (aka 15.33.x.5059), 10.18.x.5057 (aka 15.36.x.5057), 20.19.x.5063 (aka 15.40.x.5063), 21.20.x.5064 (aka 15.45.x.5064), and 24.20.100.6373 [1]. The flaw occurs in the kernel mode driver component of the graphics driver, where input validation is not properly performed, enabling memory read operations from user space.

Exploitation

An attacker must have local access to the system and be able to execute code in user mode. The vulnerability can be triggered by sending specially crafted input to the kernel mode driver via the graphics subsystem. No authentication or elevated privileges are required to reach the vulnerable code path, but the attacker must be able to interact with the driver from user space [1].

Impact

On successful exploitation, an unprivileged user can read arbitrary memory from the kernel or other processes, leading to information disclosure [1]. This could expose sensitive data such as cryptographic keys, passwords, or other confidential information resident in system memory.

Mitigation

Intel released updated driver versions that fix the vulnerability: versions 10.18.x.5059, 10.18.x.5057, 20.19.x.5063, 21.20.x.5064, and 24.20.100.6373 [1]. Users should update to these or later versions. There is no known workaround; updating the graphics driver is the only mitigation.
