JSON

A flaw was found in the tls subsystem of the Linux kernel. When setting the CRYPTO_TFM_REQ_MAY_BACKLOG flag on requests to the crypto API, crypto_aead_encrypt and crypto_aead_decrypt functions can return -EBUSY instead of -EINPROGRESS in valid situations. This issue could lead to undefined behavior and a denial of service condition.
