CVE-2026-46330

A flaw was found in the Linux kernel's TCP User-Level Protocol ULP support for SMC. This vulnerability arises when an active TCP socket is converted into an SMC socket, as the implementation attempts to modify core Virtual File System VFS structures in-place. This action violates fundamental VFS...
