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-2026-8376 in the wild and no public exploit code.\n\nAffected product: perl:perl. 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-2026-8376/ (Markdown: https://insights.sbomify.com/CVE-2026-8376/index.md)","id":"CVE-2026-8376","markdown":"https://insights.sbomify.com/CVE-2026-8376/index.md","name":"CVE-2026-8376","record":{"aliases":["AZL-87357","CLSA-2026-1780135768","CLSA-2026-1780136761","CLSA-2026-1780136870","CLSA-2026-1780391238","CLSA-2026-1780391418","CLSA-2026-1780395563","CLSA-2026-1780397181","CLSA-2026-1780398443","CLSA-2026-1780476739","CLSA-2026-1780477837","CLSA-2026-1780487743","CLSA-2026-1780510094","CLSA-2026-1780659609","CLSA-2026-1780662823","DEBIAN-CVE-2026-8376","ECHO-e5e9-738b-90e8","GHSA-mpxq-89h3-qc47","MGASA-2026-0220","MINI-f82v-xg5f-j2r6","MINI-ffj8-6p64-mrjw","MINI-jhm4-p4rg-w6fh","MINI-vmmp-85cc-hw5f","OESA-2026-2658","ROOT-OS-ALPINE-322-CVE-2026-8376","ROOT-OS-ALPINE-323-CVE-2026-8376","ROOT-OS-DEBIAN-11-CVE-2026-8376","UBUNTU-CVE-2026-8376"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl programming language","requires_auth":"none","summary":"Heap buffer overflow in Perl regex compilation on 32-bit builds allows attackers to execute code or cause denial of service via crafted regular expressions.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CPANSec","cpe":[{"product":"perl","vendor":"perl"}],"cvss":{"score":7.3,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-680","name":"Integer Overflow to Buffer Overflow"}],"description":"Perl versions before 5.40.5-RC1, from 5.41.0 before 5.42.3-RC1, from 5.43.0 before 5.43.11 have a heap buffer overflow when compiling regular expressions with a repeated fixed string on 32-bit builds.\n\nPerl_study_chunk in regcomp_study.c checked the size of the joined substring buffer in characters rather than bytes.
