[Impact]
 It was discovered that a race condition existed in the TLS subsystem in the
 Linux kernel, leading to a use-after-free or a null pointer dereference
 vulnerability. A local attacker could use this to cause a denial of service
 (system crash) or possibly execute arbitrary code.

[Potential regression]
TLS socket users will be impacted. This does not impact TLS users using
userspace TLS support.

Hangyu Hua (1):
  net: tls: fix possible race condition between do_tls_getsockopt_conf()
    and do_tls_setsockopt_conf()
