It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-88265 in the wild and no public exploit code.\n\nAffected product: Red Hat Enterprise Linux 10. 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-2026-88265/ (Markdown: https://insights.sbomify.com/CVE-2026-88265/index.md)","id":"CVE-2026-88265","markdown":"https://insights.sbomify.com/CVE-2026-88265/index.md","name":"CVE-2026-88265","record":{"aliases":["AZL-101102","BELL-CVE-2026-88265","DEBIAN-CVE-2026-88265","GHSA-cwhr-hwj2-cjrp","UBUNTU-CVE-2026-88265"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"no_fix_stated","impacts":["data_modify","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"crun container runtime","requires_auth":"low_privilege","summary":"Attackers can exploit symlink following in crun to write to host bind-mounts and change file ownership, requiring non-default /dev mounts.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":5.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"A flaw was found in crun.
