Summary

SurrealDB before 3.3.0 contains a use-after-free flaw in surrealdb-core KV backends that pass borrowed transaction state into affinitypool::spawn_local closures. A Rust embedder that leaks a dispatched future, for example with mem::forget, and then drops the transaction causes pool workers to read and write freed memory (CWE-416). A local user with low privileges can cause crashes or memory corruption, and the attack complexity is high.

Description from the CNA

SurrealDB before 3.3.0 contains a use-after-free vulnerability in surrealdb-core KV backends that pass borrowed transaction state into affinitypool::spawn_local closures relying on future Drop for safety. Rust embedders that leak a dispatched future (e.g. via mem::forget) and drop the transaction cause pool workers to read and write freed memory, risking crashes or memory corruption.
