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-2025-68744 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-2025-68744/ (Markdown: https://insights.sbomify.com/CVE-2025-68744/index.md)","id":"CVE-2025-68744","markdown":"https://insights.sbomify.com/CVE-2025-68744/index.md","name":"CVE-2025-68744","record":{"aliases":["AZL-73093","BELL-CVE-2025-68744","DEBIAN-CVE-2025-68744","GHSA-99pp-v74j-jmgv","ROOT-OS-UBUNTU-2404-CVE-2025-68744","UBUNTU-CVE-2025-68744"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel","requires_auth":"low_privilege","summary":"A missing memory free in Linux kernel BPF percpu_hash maps allows local attackers to cause memory leaks and potential denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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\nbpf: Free special fields when update [lru_,]percpu_hash maps\n\nAs [lru_,]percpu_hash maps support BPF_KPTR_{REF,PERCPU}, missing\ncalls to 'bpf_obj_free_fields()' in 'pcpu_copy_value()' could cause the\nmemory referenced by BPF_KPTR_{REF,PERCPU} fields to be held until the\nmap gets freed.\n\nFix this by calling 'bpf_obj_free_fields()' after\n'copy_map_value[,_long]()' in 'pcpu_copy_value()'.","ecosystems":[],"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":"bpf: Free special fields when update [lru_,]percpu_hash maps","id":"CVE-2025-68744","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":5,"next":{"headline":"scsi: qla2xxx: Clear cmds after chip reset","id":"CVE-2025-68745"},"packages":[],"prev":{"headline":"mshv: Fix create memory region overlap check","id":"CVE-2025-68743"},"products":["Linux"],"published":"2025-12-24","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-05-11","vendors":["Linux"]},"summary":"A missing memory free in Linux kernel BPF percpu_hash maps allows local attackers to cause memory leaks and potential denial of service.","url":"https://insights.sbomify.com/CVE-2025-68744/"}
