Description OSIDB Bzimport 2024-12-02 08:01:03 UTC 
In the Linux kernel, the following vulnerability has been resolved:

hv_sock: Initializing vsk->trans to NULL to prevent a dangling pointer

When hvs is released, there is a possibility that vsk->trans may not
be initialized to NULL, which could lead to a dangling pointer.
This issue is resolved by initializing vsk->trans to NULL.
