Description

A flaw was found in the Linux kernel's Transport Layer Security (TLS) subsystem. When processing TLS messages, a memory leak can occur if the `tls_strp_msg_hold()` function fails. This failure can lead to socket kernel buffers (skbs) being added to an internal queue but not properly released, consuming system memory. This issue could potentially lead to a Denial of Service (DoS) condition.
