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.
