{"id":"CVE-2026-35344","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-35344","summary":"uutils coreutils has an Unchecked Return Value Issue","details":"The dd utility in uutils coreutils suppresses errors during file truncation operations by unconditionally calling Result::ok() on truncation attempts. While intended to mimic GNU behavior for special files like /dev/null, the uutils implementation also hides failures on regular files and directories caused by full disks or read-only file systems. This can lead to silent data corruption in backup or migration scripts, as the utility may report a successful operation even when the destination file contains old or garbage data.","published":"2026-04-22T18:31:45Z","modified":"2026-09-10T03:50:44.848325141Z","cvss":{"score":3.3,"severity":"LOW","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"},"epss":{"score":0.00115,"percentile":0.01776,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"coreutils","fixedVersion":null}],"fix":null,"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35344"},{"type":"WEB","url":"https://github.com/uutils/coreutils/issues/9745"},{"type":"PACKAGE","url":"https://github.com/uutils/coreutils"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T03:50:44.848325141Z"}}
