An issue was discovered on Samsung mobile devices with O(8.x) and P(9.0) (Exynos 9810 chipsets) software. There is a race condition with a resultant use-after-free in the g2d driver. The Samsung ID is SVE-2018-12959 (December 2018).
The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.
