CVE-2024-46709

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/vmwgfx: Fix prime with external buffers<br /> <br /> Make sure that for external buffers mapping goes through the dma_buf<br /> interface instead of trying to access pages directly.<br /> <br /> External buffers might not provide direct access to readable/writable<br /> pages so to make sure the bo&amp;#39;s created from external dma_bufs can be<br /> read dma_buf interface has to be used.<br /> <br /> Fixes crashes in IGT&amp;#39;s kms_prime with vgem. Regular desktop usage won&amp;#39;t<br /> trigger this due to the fact that virtual machines will not have<br /> multiple GPUs but it enables better test coverage in IGT.
