CVE-2024-50264

vsock/virtio: Initialization of the dangling pointer occurring in vsk->trans

In the Linux kernel, the following vulnerability has been resolved:

vsock/virtio: Initialization of the dangling pointer occurring in vsk->trans

During loopback communication, a dangling pointer can be created in
vsk->trans, potentially leading to a Use-After-Free condition.  This
issue is resolved by initializing vsk->trans to NULL.

CWE-416 Use After Free

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
