CVE-2025-38618: vsock: Do not allow binding to VMADDR_PORT_ANY

Published Aug 22, 2025
·
Updated

In vsockbindconnectible of afvsock.c, there is a possible way to achieve code execution due to a use after free. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

Other sources

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

vsock: Do not allow binding to VMADDRPORTANY

It is possible for a vsock to autobind to VMADDRPORTANY. This can cause a use-after-free when a connection is made to the bound socket. The socket returned by accept() also has port VMADDRPORTANY but is not on the list of unbound sockets. Binding it will result in an extra refcount decrement similar to the one fixed in fcdd2242c023 (vsock: Keep the binding until socket destruction).

Modify the check in vsockbindconnectible() to also prevent binding to VMADDRPORTANY.
