https://notcve.org/view.php?id=CVE-2024-42259
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.

In the Linux kernel, the following vulnerability has been resolved: mm: huge_memory: use !CONFIG_64BIT to relax huge page alignment on 32 bit machines Yves-Alexis Perez reported commit 4ef9ad19e176 ("mm: huge_memory: don't force huge page alignment on 32 bit") didn't work for x86_32 [1]. It is because x86_32 uses CONFIG_X86_32 instead of CONFIG_32BIT. !CONFIG_64BIT should cover all 32 bit machines.
