CVE-2025-21669 - "Linux Kernel Virtio Vsock NULL Pointer Dereference"
CVE ID : CVE-2025-21669 Published : Jan. 31, 2025, 12:15 p.m. | 1 hour, 29 minutes ago Description : In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: discard packets if the transport changes If the socket has been de-assigned or assigned to another transport, we must discard any packets received because they are not expected and would cause issues when we access vsk->transport. A possible scenario is described by Hyunwoo Kim in the attached link, where after a first connect() interrupted by a signal, and a second connect() failed, we can find `vsk->transport` at NULL, leading to a NULL pointer dereference.
