An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-32810 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- crossbeam-deque (crates.io): affected all versions; fixed in 0.7.4\n- crossbeam-deque (crates.io): affected all versions; fixed in 0.7.4\n- crossbeam-deque (crates.io): affected from 0.0.0-0; fixed in 0.7.4, 0.8.1\n- crossbeam-deque (crates.io): affected from 0.8.0; fixed in 0.8.1\n- crossbeam-deque (crates.io): affected from 0.8.0; fixed in 0.8.1\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-2021-32810/ (Markdown: https://insights.sbomify.com/CVE-2021-32810/index.md)","id":"CVE-2021-32810","markdown":"https://insights.sbomify.com/CVE-2021-32810/index.md","name":"CVE-2021-32810","record":{"aliases":["DEBIAN-CVE-2021-32810","GHSA-pqqp-xmhj-wgcw","RUSTSEC-2021-0093","UBUNTU-CVE-2021-32810"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Rust work-stealing deque","requires_auth":"none","summary":"A race condition in crossbeam-deque allows tasks to be popped twice, potentially causing double frees and memory leaks in Rust applications.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"crossbeam","vendor":"crossbeam_project"},{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"crossbeam-deque is a package of work-stealing deques for building task schedulers when programming in Rust. In versions prior to 0.7.4 and 0.8.0, the result of the race condition is that one or more tasks in the worker queue can be popped twice instead of other tasks that are forgotten and never popped. If tasks are allocated on the heap, this can cause double free and a memory leak. If not, this still can cause a logical bug. Crates using `Stealer::steal`, `Stealer::steal_batch`, or `Stealer::steal_batch_and_pop` are affected by this issue. This has been fixed in crossbeam-deque 0.8.1 and 0.7.4.","ecosystems":["crates.io"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Data race in crossbeam-deque","id":"CVE-2021-32810","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"crates.io","product":"fedoraproject:fedora","products":["fedoraproject:fedora"],"type":"race_condition","year":"2021"},"n_packages":5,"n_references":15,"next":{"headline":"Remote Code Execution via Script (Python) objects under Python 3","id":"CVE-2021-32811"},"packages":[{"ecosystem":"crates.io","fixed":["0.7.4"],"introduced":["0"],"last_affected":[],"package":"crossbeam-deque","purl":null,"source":"GHSA-pqqp-xmhj-wgcw"},{"ecosystem":"crates.io","fixed":["0.7.4"],"introduced":["0"],"last_affected":[],"package":"crossbeam-deque","purl":"pkg:cargo/crossbeam-deque","source":"GHSA-pqqp-xmhj-wgcw"},{"ecosystem":"crates.io","fixed":["0.7.4","0.8.1"],"introduced":["0.0.0-0","0.8.0"],"last_affected":[],"package":"crossbeam-deque","purl":"pkg:cargo/crossbeam-deque","source":"RUSTSEC-2021-0093"},{"ecosystem":"crates.io","fixed":["0.8.1"],"introduced":["0.8.0"],"last_affected":[],"package":"crossbeam-deque","purl":null,"source":"GHSA-pqqp-xmhj-wgcw"},{"ecosystem":"crates.io","fixed":["0.8.1"],"introduced":["0.8.0"],"last_affected":[],"package":"crossbeam-deque","purl":"pkg:cargo/crossbeam-deque","source":"GHSA-pqqp-xmhj-wgcw"}],"prev":{"headline":"Arbitrary HTML injection vulnerability in ckeditor","id":"CVE-2021-32809"},"products":["crossbeam"],"published":"2021-08-02","related":[{"cvss_score":9.8,"headline":"Double free in crossbeam","id":"CVE-2018-20996","kev_date_added":null,"published":"2019-08-26"},{"cvss_score":8.1,"headline":"Improper Restriction of Operations within the Bounds of a Memory Buffer and Race Condition in crossbeam-utils","id":"CVE-2022-23639","kev_date_added":null,"published":"2022-02-15"},{"cvss_score":8.1,"headline":"Undefined Behavior in bounded Crossbeam channel","id":"CVE-2020-15254","kev_date_added":null,"published":"2020-10-16"}],"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":"open","licence":"CC0 1.0","name":"RustSec","prefix":"RUSTSEC"},{"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["crossbeam-rs"]},"summary":"A race condition in crossbeam-deque allows tasks to be popped twice, potentially causing double frees and memory leaks in Rust applications.","url":"https://insights.sbomify.com/CVE-2021-32810/"}
