This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
drm/i915/gem: Fix Virtual Memory mapping boundaries calculation
Calculating the size of the mapped area as the lesser value
between the requested size and the actual size does not consider
the partial mapping offset. This can cause page fault access.
Fix the calculation of the starting and ending addresses, the
total size is now deduced from the difference between the end and
start addresses.
Additionally, the calculations have been rewritten in a clearer
and more understandable form.
[Joonas: Add Requires: tag]
Requires: 60a2066c5005 ("drm/i915/gem: Adjust vma offset for framebuffer mmap offset")
(cherry picked from commit 97b6784753da06d9d40232328efc5c5367e53417)
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
