CVE-2025-21854

The CVE-2025-21854 issue affects the Linux kernel sockmap/vsock path. It occurs when a connectible (unconnected) vsock may lose its prior transport, potentially causing a NULL dereference in the BPF recv path and a crash when a listening vsock is present in a sockmap. The root cause is that sockm...
