In the Linux kernel, the following vulnerability has been resolved:
crypto: krb5 - use kfree_sensitive() for derived key buffers
crypto_krb5_prepare_encryption() and crypto_krb5_prepare_checksum()
free the buffer holding the freshly derived keys with plain kfree(),
leaving the key material behind in the freed slab object.
