How to fix?

There is no fixed version for Debian:unstable pgvector.

NVD Description

Note: Versions mentioned in the description apply only to the upstream pgvector package and not the pgvector package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

Integer wraparound in IVFFlat index build in pgvector before 0.8.6 allows a database user to write data out-of-bounds, which could lead to arbitrary code execution. Only 32-bit systems are affected.
