  "description": "In the Linux kernel, the following vulnerability has been resolved:  drm/i915: Fix potential bit_17 double-free  A userspace with multiple threads racing I915_GEM_SET_TILING to set the tiling to I915_TILING_NONE could trigger a double free of the bit_17 bitmask.  (Or conversely leak memory on the transition to tiled.)  Move allocation/free\u0027ing of the bitmask within the section protected by the obj lock.
