An issue where a provided address with access_ok() is not checked was discovered in i915_gem_execbuffer2_ioctl in drivers/gpu/drm/i915/i915_gem_execbuffer.c in the Linux kernel through 4.19.13. A local attacker can craft a malicious IOCTL function call to overwrite arbitrary kernel memory, resulting in a Denial of Service or privilege escalation.

CVE-2018-20669 [HIGH] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Timothy Michaud discovered that the i915 graphics driver in the Linux
kernel did not properly validate user memory locations for the
i915_gem_execbuffer2_ioctl. A local attacker could possibly use this to
cause a denial of service or execute arbitrary code. (CVE-2018-20669)
It was discovered that the Kvaser CAN/USB driver in the Linux kernel did
not properly initialize memory in certain situations. A local attacker
could possibly use this to expose sensitive information (kernel memory).

A flaw was found in the Linux kernel where a provided address with access_ok() is not checked before accessing userspace data in certain situations.

CVE-2018-20669 CVE-2018-20669: In i915_gem_execbuffer2_ioctl of i915_gem_execbuffer
In i915_gem_execbuffer2_ioctl of i915_gem_execbuffer.c, there is a possible arbitrary kernel memory write due to a missing validation of a userspace pointer. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

CVE-2018-20669 kernel: missing access_ok() checks in i915_gem_execbuffer2_ioctl() results in priviledge escalation
Linux kernel is not checking a provided address with access_ok() when accessing userspace data in certain situations. Lack of such checks in i915_gem_execbuffer2_ioctl in drivers/gpu/drm/i915/i915_gem_execbuffer.c may allow a local unprivileged attacker to possible escalate its privileges.
