If the record\nhas already been decrypted (which may be the case for TLS 1.3 where\nwe don't know type until decryption) we queue the pending record\nto the rx_list. Next recvmsg() will pick it up from there.\n\nQueuing the skb to rx_list after zero-copy decrypt is not possible,\nsince in that case we decrypted directly to the user space buffer,\nand we don't have an skb to queue (darg.skb points to the ciphertext\nskb for access to metadata like length).\n\nOnly data records are allowed zero-copy, and we break the processing\nloop after each non-data record. So we should never zero-copy and\nthen find out that the record type has changed. The corner case\nwe missed is when the initial record comes from rx_list, and it's\nzero length.","2025-09-05",9.8,"v3.1","Critical",0.0288,{"cveId":35,"description":36,"publishedDate":11,"cvssScore":30,"cvssVersion":31,"severity":32,"isKev":15,"epssScore":37},"CVE-2024-32740","A vulnerability has been identified in SIMATIC CN 4100 (All versions \u003C V3.0).
