CVE-2026-46234

CVE-2026-46234 affects the Linux kernel vsock code, specifically the vsock_update_buffer_size path. The bug arises from clamping the buffer size: it first enforces the maximum, then the minimum, which allows vsk->buffer_size to exceed vsk->buffer_max_size when a larger minimum is configured...
