The issue is related to a race condition in the Linux kernel's TLS protocol implementation, specifically in the `do tls getsockopt conf()` and `do tls setsockopt conf()` functions in the `net/tls/tls main.c` module. This is due to the lack of synchronization in `do tls getsockopt conf()`, allowing for concurrent access to `ctx->crypto send.info`. Exploitation of this issue can lead to a denial of service. The `do tls getsockopt` function lacks a `lock sock` call, resulting in a race condition that can cause a use-after-free or NULL pointer dereference.
