Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-41035 in the wild and no public exploit code.\n\nAffected product: Samba rsync. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-41035/ (Markdown: https://insights.sbomify.com/CVE-2026-41035/index.md)","id":"CVE-2026-41035","markdown":"https://insights.sbomify.com/CVE-2026-41035/index.md","name":"CVE-2026-41035","record":{"aliases":["ALPINE-CVE-2026-41035","ALSA-2026:17481","ALSA-2026:19152","AZL-82958","BELL-CVE-2026-41035","CLSA-2026-1778940132","CLSA-2026-1779131668","CLSA-2026-1779154430","CLSA-2026-1780054763","CLSA-2026-1780054955","CLSA-2026-1780055137","CLSA-2026-1780062116","CLSA-2026-1780062671","CLSA-2026-1780064425","CLSA-2026-1780066764","CLSA-2026-1780388397","CLSA-2026-1780388593","CLSA-2026-1780389337","DEBIAN-CVE-2026-41035","ECHO-96cc-2c47-feab","GHSA-m34r-4v3r-pp9v","JLSEC-2026-627","MGASA-2026-0101","OESA-2026-2150","RHSA-2026:17481","RHSA-2026:19152","RHSA-2026:20601","RHSA-2026:25149","RHSA-2026:25170","RHSA-2026:25172","RHSA-2026:25173","RHSA-2026:25190","RLSA-2026:17481","RLSA-2026:19152","SUSE-SU-2026:2002-1","SUSE-SU-2026:21676-1","SUSE-SU-2026:21686-1","UBUNTU-CVE-2026-41035","openSUSE-SU-2026:10775-1"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"rsync file synchronization","requires_auth":"low_privilege","summary":"An attacker can trigger a use-after-free in rsync when the receiver uses the -X flag, potentially leading to code execution or denial of service.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"rsync","vendor":"samba"}],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-805","name":"Buffer Access with Incorrect Length Value"},{"id":"CWE-130","name":"Improper Handling of Length Parameter Inconsistency"}],"description":"In rsync 3.0.1 through 3.4.1, receive_xattr relies on an untrusted length value during a qsort call, leading to a receiver use-after-free.
