{"id":"CVE-2025-38202","summary":"bpf: Check rcu_read_lock_trace_held() in bpf_map_lookup_percpu_elem()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Check rcu_read_lock_trace_held() in bpf_map_lookup_percpu_elem()\n\nbpf_map_lookup_percpu_elem() helper is also available for sleepable bpf\nprogram. When BPF JIT is disabled or under 32-bit host,\nbpf_map_lookup_percpu_elem() will not be inlined. Using it in a\nsleepable bpf program will trigger the warning in\nbpf_map_lookup_percpu_elem(), because the bpf program only holds\nrcu_read_lock_trace lock. Therefore, add the missed check.","modified":"2026-04-16T04:33:54.342419690Z","published":"2025-07-04T13:37:23.347Z","related":["SUSE-SU-2025:02853-1","SUSE-SU-2025:02923-1","SUSE-SU-2025:02969-1","SUSE-SU-2025:02996-1","SUSE-SU-2025:02997-1","SUSE-SU-2025:03011-1","SUSE-SU-2025:03023-1","SUSE-SU-2025:20577-1","SUSE-SU-2025:20586-1","SUSE-SU-2025:20601-1","SUSE-SU-2025:20602-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38202.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2d834477bbc1e8b8a59ff8b0c081529d6bed7b22"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2f8c69a72e8ad87b36b8052f789da3cc2b2e186c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7bf4461f1c97207fda757014690d55a447ce859f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b522d4d334f206284b1a44b0b0b2f99fd443b39b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d4965578267e2e81f67c86e2608481e77e9c8569"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/10/msg00008.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38202.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38202"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"07343110b293456d30393e89b86c4dee1ac051c8"},{"fixed":"2f8c69a72e8ad87b36b8052f789da3cc2b2e186c"},{"fixed":"7bf4461f1c97207fda757014690d55a447ce859f"},{"fixed":"2d834477bbc1e8b8a59ff8b0c081529d6bed7b22"},{"fixed":"b522d4d334f206284b1a44b0b0b2f99fd443b39b"},{"fixed":"d4965578267e2e81f67c86e2608481e77e9c8569"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-38202.json"}}],"schema_version":"1.7.5"}
