Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
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.

No action by another user or administrator is required.\nS:U - The invalid page mappings and memcpy corruption stay inside the guest kernel\u0027s own security authority; this is a guest DRM driver bug, not a hypervisor or IOMMU boundary crossing.\nC:H - vmw_bo_cpu_blit_line() kmap_atomic()s attacker-influenced, non-CPU-mappable page pointers derived from the imported sg table and memcpys from them into the display surface\u0027s buffer, which userspace can read back via VMW_PRESENT_READBACK \u2014 disclosing arbitrary kernel memory.\nI:H - In the readback direction the external bo is the memcpy destination, so attacker-controlled framebuffer bytes are written through those bogus page pointers into unrelated kernel memory, giving a kernel write primitive.\nA:H - The maintainer states the change \"fixes crashes in IGT\u0027s kms_prime with vgem\"; dereferencing invalid page pointers under kmap_atomic (preemption and page faults disabled) reliably oopses or panics the kernel."
