They also could lead to uninitialized memory being dropped if the field for which the offset is requested was behind a deref coercion, and that deref coercion caused a panic. The flaw was corrected by using MaybeUninit.","published":"2019-08-26T15:15:12.127Z","modified":"2026-07-08T15:55:41.479478Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"memoffset","fixedVersion":"0.5.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/Gilnaa/memoffset/issues/9#issuecomment-505461490"},{"type":"ADVISORY","url":"https://rustsec.org/advisories/RUSTSEC-2019-0011.html"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2019-15553"},{"type":"PACKAGE","url":"https://github.com/Gilnaa/memoffset"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-08T15:55:41.479478Z"}}
