CVE-2024-46709

  3. CVE-2024-46709
In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Fix prime with external buffers Make sure that for external buffers mapping goes through the dma_buf interface instead of trying to access pages directly. External buffers might not provide direct access to readable/writable pages so to make sure the bo's created from external dma_bufs can be read dma_buf interface has to be used. Fixes crashes in IGT's kms_prime with vgem. Regular desktop usage won't trigger this due to the fact that virtual machines will not have multiple GPUs but it enables better test coverage in IGT.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/vmwgfx: Corrige prime con búferes externos Asegúrate de que el mapeo de búferes externos pase por la interfaz dma_buf en lugar de intentar acceder a las páginas directamente. Los búferes externos podrían no proporcionar acceso directo a páginas legibles/escribibles, así que para asegurarse de que los bo creados a partir de dma_bufs externos puedan leerse, se debe usar la interfaz dma_buf. Corrige fallas en kms_prime de IGT con vgem. El uso regular del escritorio no activará esto debido al hecho de que las máquinas virtuales no tendrán múltiples GPU, pero permite una mejor cobertura de pruebas en IGT.
