kernel: drm/i915: mark requests for GuC virtual engines to avoid use-after-free

A use-after-free vulnerability was found in the Linux kernel Intel i915 graphics driver's GuC virtual engine request handling. A local user with access to GPU rendering can create requests on GuC virtual engines and trap references via syncfile or dmabuf, causing fence release operations to acces...

kernel: dma-buf/dma-resv: check if the new fence is really later

In the Linux kernel, the following vulnerability has been resolved: dma-buf/dma-resv: check if the new fence is really later Previously when we added a fence to a dmaresv object we always assumed the the newer than all the existing fences. With Jason's work to add an UAPI to explicit export/impor...

kernel: Double-free in split_2MB_gtt_entry when function intel_gvt_dma_map_guest_page failed

A double-free memory flaw was found in the Linux kernel. The Intel GVT-g graphics driver triggers VGA card system resource overload, causing a fail in the intelgvtdmamapguestpage function. This issue could allow a local user to crash the system...
