Vulnerability Title
drm/msm/a6xx: Avoid a nullptr dereference when speedbin setting fails
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: drm/msm/a6xx: Avoid a nullptr dereference when speedbin setting fails Calling a6xx_destroy() before adreno_gpu_init() leads to a null pointer dereference on: msm_gpu_cleanup() : platform_set_drvdata(gpu->pdev, NULL); as gpu->pdev is only assigned in: a6xx_gpu_init() |_ adreno_gpu_init |_ msm_gpu_init() Instead of relying on handwavy null checks down the cleanup chain, explicitly de-allocate the LLC data and free a6xx_gpu instead.
