CVE-2026-74613

A flaw was found in the Linux kernel's vsock/virtio component. A race condition during the teardown of the receive RX queue can allow work to add buffers after the virtual queues virtqueues have been deleted. This can lead to a use-after-free vulnerability, which may result in a kernel panic and ...

kernel: vsock: Keep the binding until socket destruction

A flaw was found in the Linux kernel's virtual socket protocol network driver, where an improperly timed socket unbinding could result in a use-after-free issue. This flaw allows an attacker who can create and destroy arbitrary connections on virtual connections to read or modify system memory,...

CVE-2025-21756 vsock: Keep the binding until socket destruction

In the Linux kernel, the following vulnerability has been resolved: vsock: Keep the binding until socket destruction Preserve sockets bindings; this includes both resulting from an explicit bind and those implicitly bound through autobind during connect. Prevents socket unbinding during a transpo...

kernel: vsock: remove vsock from connected table when connect is interrupted by a signal

A vulnerability was found in the Linux kernel's vsock subsystem's vsockstreamconnect function where improper handling of the socket state can lead to the connected table's list being corrupted. This occurs when a signal interrupt occurs and resets the socket's state without removing it from the...
