If an element's `Drop` panics during the drop, that update is never reached, so the collection still treats the already-dropped elements as live. When the collection is later dropped (its destructor walks the range described by the stale metadata), or a subsequent operation touches the same slots, those elements are dropped a second time — a double free (CWE-415) / use-after-free (CWE-416) reachable from safe Rust.\n\nThe stale field is `left` and `right` for `Chunk::clear`, `left` for `drop_left`, `right` for `drop_right`, and the length field for both `InlineArray` methods.\n\n## Mitigation\n\nUpgrade to `imbl-sized-chunks` 0.2.0 or later, which commits the metadata before dropping any element (fixed in jneem/imbl-sized-chunks#14, released in 0.2.0).","state":0,"publishedAt":"2026-09-04T12:00:00+00:00","modifiedAt":"2026-09-21T09:15:02.898994+00:00","affected":[{"ecosystem":"crates.io","name":"imbl-sized-chunks","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0.0.0-0"},{"kind":"fixed","version":"0.2.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[],"references":["https://crates.io/crates/imbl-sized-chunks","https://rustsec.org/advisories/RUSTSEC-2026-0292.html","https://github.com/jneem/imbl-sized-chunks/pull/14"],"sourceUrl":"https://osv.dev/vulnerability/RUSTSEC-2026-0292","license":"OSV · upstream source license applies","key":"osv:RUSTSEC-2026-0292","identifiers":["RUSTSEC-2026-0292"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
