  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\npmdomain: mediatek: mfg: initialize prev_o in mtk_mfg_attach_dev()\n\nmtk_mfg_attach_dev() reads prev_o on the first iteration of its loop,\nin \"if (prev_o \u0026\u0026 prev_o-\u003efreq == o-\u003efreq)\", before prev_o is assigned\nat the end of the loop body. On that first iteration, evaluating prev_o\nreads an indeterminate value. If it is non-NULL, the condition\ndereferences a stale or invalid pointer, potentially faulting or\nincorrectly skipping the first OPP.\n\nInitialize prev_o to NULL. This matches the intent as well: there is no\nprevious OPP to compare against on the first iteration.\n\nFound with Clang's -Wconditional-uninitialized.",
