In the Linux kernel, the following vulnerability has been resolved:
selinux: use sk blob accessor in socket permission helpers
SELinux socket state lives in the composite LSM socket blob.
sock_has_perm() and nlmsg_sock_has_extended_perms() currently
dereference sk->sk_security directly, which assumes the SELinux socket
blob is at offset zero.
In stacked configurations that assumption does not hold. If another LSM
allocates socket blob storage before SELinux, these helpers may read the
wrong blob and feed invalid SID and class values into AVC checks.
Use selinux_sock() instead of accessing sk->sk_security directly.
