Answer in brief
CVE-2022-46149 records a Unknown severity vulnerability in out-of-bounds read possible when setting list-of-pointers. The current sources do not mark it as known exploited. The current feed maps capnp (crates.io). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

If a message consumer expects data of type "list of pointers", and if the consumer performs certain specific actions on such data, then a message producer can cause the consumer to read out-of-bounds memory. This could trigger a process crash in the consumer, or in some cases could allow exfiltration of private in-memory data. The C++ Cap'n Proto library is also affected by this bug. See the [advisory](https://github.com/capnproto/capnproto/tree/master/security-advisories/2022-11-30-0-pointer-list-bounds.md) on the main Cap'n Proto repo for a succinct description of the exact circumstances in which the problem can arise.
