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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/2d834477bbc1e8b8a59ff8b0c081529d6bed7b22","https://git.kernel.org/stable/c/2f8c69a72e8ad87b36b8052f789da3cc2b2e186c","https://git.kernel.org/stable/c/7bf4461f1c97207fda757014690d55a447ce859f","https://git.kernel.org/stable/c/b522d4d334f206284b1a44b0b0b2f99fd443b39b","https://git.kernel.org/stable/c/d4965578267e2e81f67c86e2608481e77e9c8569"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:04:28.436527499+00:00"},"epss":{"cve":"CVE-2025-38202","score":0.0018,"percentile":0.07557,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
