In the Linux kernel, the following vulnerability has been resolved: drm/msm/a6xx: Avoid a nullptr dereference when speedbin setting fails Calling a6xxdestroy() before adrenogpuinit() leads to a null pointer dereference on: msmgpucleanup() : platformsetdrvdata(gpu->pdev, NULL); as gpu->pdev is only assigned in: a6xxgpuinit() | adrenogpuinit |_ msmgpuinit() Instead of relying on handwavy null checks down the cleanup chain, explicitly de-allocate the LLC data and free a6xx_gpu instead.
