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.

ASB-A-1353682282020-07-01vendor · osvUS
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.
