CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2024-42262 – drm/v3d: Fix potential memory leak in the performance extension
https://notcve.org/view.php?id=CVE-2024-42262
In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Fix potential memory leak in the performance extension If fetching of userspace memory fails during the main loop, all drm sync objs looked up until that point will be leaked because of the missing drm_syncobj_put. Fix it by exporting and using a common cleanup helper.

https://notcve.org/view.php?id=CVE-2024-42261
In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Validate passed in drm syncobj handles in the timestamp extension If userspace provides an unknown or invalid handle anywhere in the handle array the rest of the driver will not handle that well. Fix it by checking handle was looked up successfully or otherwise fail the extension by jumping into the existing unwind.

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.

https://notcve.org/view.php?id=CVE-2024-42258
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.
