In the Linux kernel, the following vulnerability has been resolved:
drm/i915: Fix potential bit_17 double-free
A userspace with multiple threads racing I915GEMSETTILING to set the tiling to I915TILINGNONE could trigger a double free of the bit17 bitmask. (Or conversely leak memory on the transition to tiled.) Move allocation/free'ing of the bitmask within the section protected by the obj lock.
[tursulin: Correct fixes tag and added cc stable.] (cherry picked from commit 10e0cbaaf1104f449d695c80bcacf930dcd3c42e)
