In the Linux kernel, the following vulnerability has been resolved:
net/tls: fix slab-out-of-bounds bug in decrypt_internal
The memory size of tlsctx->rx.iv for AES128-CCM is 12 setting in tlssetswoffload(). The return value of cryptoaeadivsize() for "ccm(aes)" is 16. So memcpy() require 16 bytes from 12 bytes memory space will trigger slab-out-of-bounds bug as following:
================================================================== BUG: KASAN: slab-out-of-bounds in decrypt_internal+0x385/0xc40 [tls] Read of size 16 at addr ffff888114e84e60 by task tls/10911

Replace the cryptoaeadivsize() with prot->ivsize + prot->saltsize when memcpy() iv value in TLS13_VERSION scenario.
