  "description": "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 tls_ctx-\u003Erx.iv for AES128-CCM is 12 setting in tls_set_sw_offload(). The return value of crypto_aead_ivsize() for \u0022ccm(aes)\u0022 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\u002B0x385/0xc40 [tls] Read of size 16 at addr ffff888114e84e60 by task tls/10911  Call Trace:  \u003CTASK\u003E  dump_stack_lvl\u002B0x34/0x44  print_report.cold\u002B0x5e/0x5db  ? decrypt_internal\u002B0x385/0xc40 [tls]  kasan_report\u002B0xab/0x120  ? decrypt_internal\u002B0x385/0xc40 [tls]  kasan_check_range\u002B0xf9/0x1e0  memcpy\u002B0x20/0x60  decrypt_internal\u002B0x385/0xc40 [tls]  ? tls_get_rec\u002B0x2e0/0x2e0 [tls]  ? process_rx_list\u002B0x1a5/0x420 [tls]  ? tls_setup_from_iter.constprop.0\u002B0x2e0/0x2e0 [tls]  decrypt_skb_update\u002B0x9d/0x400 [tls]  tls_sw_recvmsg\u002B0x3c8/0xb50 [tls]  Allocated by task 10911:  kasan_save_stack\u002B0x1e/0x40  __kasan_kmalloc\u002B0x81/0xa0  tls_set_sw_offload\u002B0x2eb/0xa20 [tls]  tls_setsockopt\u002B0x68c/0x700 [tls]  __sys_setsockopt\u002B0xfe/0x1b0  Replace the crypto_aead_ivsize() with prot-\u003Eiv_size \u002B prot-\u003Esalt_size when memcpy() iv value in TLS_1_3_VERSION scenario.",
