In the Linux kernel, the following vulnerability has been resolved:

crypto: algif_hash - fix double free in hash_accept

If accept(2) is called on socket type algif_hash with
MSG_MORE flag set and crypto_ahash_import fails,
sk2 is freed. However, it is also freed in af_alg_release,
leading to slab-use-after-free error.
