Technical Description
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/gem: add missing boundary check in vm_access
A missing bounds check in vm_access() can lead to an out-of-bounds read
or write in the adjacent memory area, since the len attribute is not
validated before the memcpy later in the function, potentially hitting:
