Description
do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading to a race condition (with a resultant use-after-free or NULL pointer dereference).
A use-after-free flaw was found in the do_tls_getsockopt function in net/tls/tls_main.c in the Transport Layer Security (TLS) in the Network subcompact in the Linux kernel. This flaw allows an attacker to cause a NULL pointer dereference problem due to a race condition.
