In the Linux kernel, the following vulnerability has been resolved:
hwrng: core - fix rng list on registration error
hwrng_register(rng) does the following:
- Checks if rng has name and read methods set
- Checks if the name already exists
- Adds rng to global rng_list
- May try to set rng to current_rng
If step 4 fails, it returns an error. However, it does not remove the rng from rng_list, causing a dangling reference which can result in use-after-free if the caller frees rng, since registration failed.
Add a list_del_init() cleanup step.
