"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nhwrng: core - fix rng list on registration error\n\nhwrng_register(rng) does the following:\n\n1. Checks if rng has name and read methods set\n2. Checks if the name already exists\n3. Adds rng to global rng_list\n4. May try to set rng to current_rng\n\nIf step 4 fails, it returns an error. However, it does not remove the\nrng from rng_list, causing a dangling reference which can result in\nuse-after-free if the caller frees rng, since registration failed.\n\nAdd a list_del_init() cleanup step."
