CVE-2024-42259

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/i915/gem: Fix Virtual Memory mapping boundaries calculation<br /> <br /> Calculating the size of the mapped area as the lesser value<br /> between the requested size and the actual size does not consider<br /> the partial mapping offset. This can cause page fault access.<br /> <br /> Fix the calculation of the starting and ending addresses, the<br /> total size is now deduced from the difference between the end and<br /> start addresses.<br /> <br /> Additionally, the calculations have been rewritten in a clearer<br /> and more understandable form.<br /> <br /> [Joonas: Add Requires: tag]<br /> Requires: 60a2066c5005 ("drm/i915/gem: Adjust vma offset for framebuffer mmap offset")<br /> (cherry picked from commit 97b6784753da06d9d40232328efc5c5367e53417)
