{"id":"UBUNTU-CVE-2026-35360","details":"The touch utility in uutils coreutils is vulnerable to a Time-of-Check to Time-of-Use (TOCTOU) race condition during file creation. When the utility identifies a missing path, it later attempts creation using File::create(), which internally uses O_TRUNC. An attacker can exploit this window to create a file or swap a symlink at the target path, causing touch to truncate an existing file and leading to permanent data loss.","modified":"2026-09-21T21:39:22.669942813Z","published":"2026-04-22T17:16:00Z","upstream":["CVE-2026-35360"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-35360"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-35360"},{"type":"REPORT","url":"https://github.com/uutils/coreutils/issues/10019"}],"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_name":"rust-coreutils","binary_version":"0.0.24-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35360.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-2026-35360.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_name":"rust-coreutils","binary_version":"0.10.0-1ubuntu2~26.04.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35360.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
