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-2026-97568 in the wild and no public exploit code.\n\nAffected product: Linux. 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-2026-97568/ (Markdown: https://insights.sbomify.com/CVE-2026-97568/index.md)","id":"CVE-2026-97568","markdown":"https://insights.sbomify.com/CVE-2026-97568/index.md","name":"CVE-2026-97568","record":{"aliases":["AZL-104529","BELL-CVE-2026-97568","DEBIAN-CVE-2026-97568","GHSA-6cg2-hrxf-655w","UBUNTU-CVE-2026-97568"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux kernel","requires_auth":"none","summary":"An uninitialized memory read in the Linux kernel MPTCP subsystem may leak sensitive kernel memory to remote attackers.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nmptcp: syncookies: remember the request backup flag\n\nInstead of using an uninitialised bit when copying the info in\nsubflow_ulp_clone().\n\nTo fix this, no need to extend the join_entry structure: backup is\ncoming from struct mptcp_subflow_request_sock, only one bit.
