It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-35378 exists.\n\nAffected packages and fixed versions:\n- coreutils (crates.io): affected all versions; fixed in 0.8.0\n- coreutils (crates.io): affected all versions; fixed in 0.8.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-35378/ (Markdown: https://insights.sbomify.com/CVE-2026-35378/index.md)","id":"CVE-2026-35378","markdown":"https://insights.sbomify.com/CVE-2026-35378/index.md","name":"CVE-2026-35378","record":{"aliases":["DEBIAN-CVE-2026-35378","GHSA-5pv5-xh52-hvrp","UBUNTU-CVE-2026-35378"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"coreutils expr utility","requires_auth":"low_privilege","summary":"A logic error in uutils coreutils expr causes premature script termination by failing to short-circuit logical operations, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"coreutils","vendor":"uutils"}],"cvss":{"score":3.3,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-768","name":"Incorrect Short Circuit Evaluation"}],"description":"A logic error in the expr utility of uutils coreutils causes the program to evaluate parenthesized subexpressions during the parsing phase rather than at the execution phase. This implementation flaw prevents the utility from performing proper short-circuiting for logical OR (|) and AND (\u0026) operations. As a result, arithmetic errors (such as division by zero) occurring within \"dead\" branches, branches that should be ignored due to short-circuiting, are raised as fatal errors. This divergence from GNU expr behavior can cause guarded expressions within shell scripts to fail with hard errors instead of returning expected boolean results, leading to premature script termination and breaking GNU-compatible shell control flow.","ecosystems":["crates.io"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"uutils coreutils expr Local Denial of Service via Eager Evaluation of Parenthesized Subexpressions","id":"CVE-2026-35378","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":2,"n_references":2,"next":{"headline":"uutils coreutils tr Local Logic Error and Data Integrity Issue in Character Class Handling","id":"CVE-2026-35379"},"packages":[{"ecosystem":"crates.io","fixed":["0.8.0"],"introduced":["0"],"last_affected":[],"package":"coreutils","purl":null,"source":"GHSA-5pv5-xh52-hvrp"},{"ecosystem":"crates.io","fixed":["0.8.0"],"introduced":["0"],"last_affected":[],"package":"coreutils","purl":"pkg:cargo/coreutils","source":"GHSA-5pv5-xh52-hvrp"}],"prev":{"headline":"uutils coreutils env Local Denial of Service via Improper Handling of Backslashes in Split-String Mode","id":"CVE-2026-35377"},"products":["coreutils"],"published":"2026-04-22","related":[{"cvss_score":7.3,"headline":"uutils coreutils chmod Path Traversal Bypass of --preserve-root","id":"CVE-2026-35338","kev_date_added":null,"published":"2026-04-22"},{"cvss_score":7.2,"headline":"uutils coreutils chroot Local Privilege Escalation and chroot Escape in via Name Service Switch (NSS) Injection","id":"CVE-2026-35368","kev_date_added":null,"published":"2026-04-22"},{"cvss_score":7.1,"headline":"uutils coreutils mkfifo Unauthorized Permission Change on Existing Files","id":"CVE-2026-35341","kev_date_added":null,"published":"2026-04-22"},{"cvss_score":7,"headline":"uutils coreutils mkfifo Privilege Escalation via TOCTOU Race Condition","id":"CVE-2026-35352","kev_date_added":null,"published":"2026-04-22"},{"cvss_score":6.7,"headline":"uutils coreutils Path-Based Safety Bypass with --preserve-root","id":"CVE-2026-35349","kev_date_added":null,"published":"2026-04-22"},{"cvss_score":6.6,"headline":"uutils coreutils cp Unexpected Privileged Executable Creation with -p","id":"CVE-2026-35350","kev_date_added":null,"published":"2026-04-22"},{"cvss_score":6.6,"headline":"uutils coreutils mv Denial of Service and Data Duplication via Improper Symlink Expansion","id":"CVE-2026-35365","kev_date_added":null,"published":"2026-04-22"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-22","vendors":["Uutils"]},"summary":"A logic error in uutils coreutils expr causes premature script termination by failing to short-circuit logical operations, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2026-35378/"}
