Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the calculation of Virtual Memory mapping boundaries in the Linux kernel's drm/i915/gem component. The calculation does not consider the partial mapping offset, which can cause page fault access. The fix involves recalculating the starting and ending addresses and deducing the total size from the difference between the end and start addresses. The calculations have been rewritten for clarity and understandability.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
