CVE-2026-46330 is a high-severity vulnerability in the Linux kernel related to the TCP ULP support for SMC. The feature attempted to convert an active TCP socket into an SMC socket by modifying core file system structures in-place, violating VFS invariants. This design flaw risks use-after-free errors and system instability. The vulnerability has been addressed by reverting the problematic commit and removing the feature entirely.
