In the Linux kernel, the following vulnerability has been resolved: crypto: bcm - add error check in the ahash_hmac_init function The ahash_init functions may return fails. The ahash_hmac_init should not return ok when ahash_init returns error. For an example, ahash_init will return -ENOMEM when allocation memory is error.
