Description OSIDB Bzimport 2025-07-25 14:03:52 UTC 
In the Linux kernel, the following vulnerability has been resolved:

vsock/vmci: Clear the vmci transport packet properly when initializing it

In vmci_transport_packet_init memset the vmci_transport_packet before
populating the fields to avoid any uninitialised data being left in the
structure.
