HighCVSS 7.8/10Last modified Jun 17, 2026

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'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)
