      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/msm/adreno: Asignar msm_gpu->pdev antes para evitar nullptrs Hay algunos casos, como el descubierto por Commit 46d4efcccc68 (\"drm/msm/a6xx: Evitar una desreferencia nullptr cuando fallo la configuraci\u00f3n de speedbin\") donde msm_gpu_cleanup() : platform_set_drvdata(gpu->pdev, NULL); se llama en gpu->pdev == NULL, ya que el dispositivo GPU a\u00fan no se ha inicializado por completo. Resulta que hay m\u00e1s que solo la ruta mencionada anteriormente que hace que esto suceda (por ejemplo, el caso cuando hay datos de speedbin en el cat\u00e1logo, pero opp-supported-hw falta en DT). Asignar msm_gpu->pdev antes parece ser la soluci\u00f3n menos dolorosa para esto, as\u00ed que hazlo. Parche: https://patchwork.freedesktop.org/patch/602742/"
