In the Linux kernel, the following vulnerability has been resolved:
vsock: Fix transport_{g2h,h2g} TOCTOU
vsockfindcid() and vsockdevdoioctl() may race with module unload. transport{g2h,h2g} may become NULL after the NULL check.
Introduce vsocktransportlocal_cid() to protect from a potential null-ptr-deref.
