{"id":"UBUNTU-CVE-2026-35344","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.","modified":"2026-09-21T21:39:07.669247322Z","published":"2026-04-22T17:16:00Z","upstream":["CVE-2026-35344"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-35344"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-35344"},{"type":"REPORT","url":"https://github.com/uutils/coreutils/issues/9745"}],"affected":[{"package":{"name":"rust-coreutils","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/rust-coreutils?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.20-1","0.0.22-1","0.0.23-1","0.0.23-2","0.0.23-3","0.0.24-1","0.0.24-2"],"ecosystem_specific":{"binaries":[{"binary_version":"0.0.24-2","binary_name":"rust-coreutils"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35344.json"}},{"package":{"name":"rust-coreutils","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/rust-coreutils?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.30-1","0.0.30-2","0.0.30-2ubuntu2","0.1.0-0ubuntu1","0.1.0+git20250711.2ba3a33-0ubuntu1","0.1.0+git20250711.2ba3a33-0ubuntu2","0.1.0+git20250711.2ba3a33-0ubuntu3","0.1.0+git20250711.2ba3a33-0ubuntu4","0.1.0+git20250801.cf79675-0ubuntu1","0.1.0+git20250813.4af2a84-0ubuntu2","0.1.0+git20250813.4af2a84-0ubuntu4","0.1.0+git20250813.4af2a84-0ubuntu6","0.1.0+git20250813.4af2a84-0ubuntu7","0.2.2-0ubuntu1","0.2.2-0ubuntu2","0.2.2-0ubuntu2.1"],"ecosystem_specific":{"binaries":[{"binary_name":"rust-coreutils","binary_version":"0.2.2-0ubuntu2.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35344.json"}},{"package":{"name":"rust-coreutils","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/rust-coreutils?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.2.2-0ubuntu2","0.2.2-0ubuntu4","0.5.0-0ubuntu1","0.5.0-0ubuntu2","0.6.0-0ubuntu1","0.7.0-0ubuntu1","0.8.0-0ubuntu3","0.10.0-1ubuntu2~26.04.1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.10.0-1ubuntu2~26.04.1","binary_name":"rust-coreutils"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35344.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"},{"type":"Ubuntu","score":"medium"}]}
