CVE-2025-21756

CVE-2025-21756 affects the Linux kernel vsock subsystem. The issue arises from keeping socket bindings until destruction, preventing correct unbinding during transport reassignment. This leads to a use-after-free in the binding path, observed as a KASAN slab-use-after-free in __vsock_bind and rel...
