  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/msm/dpu: check for valid hw_pp in dpu_encoder_helper_phys_cleanup\n\nThe commit 8b45a26f2ba9 (\"drm/msm/dpu: reserve cdm blocks for writeback\nin case of YUV output\") introduced a smatch warning about another\nconditional block in dpu_encoder_helper_phys_cleanup() which had assumed\nhw_pp will always be valid which may not necessarily be true.\n\nLets fix the other conditional block by making sure hw_pp is valid\nbefore dereferencing it.\n\nPatchwork: https://patchwork.freedesktop.org/patch/574878/",
