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.\n\n## Affected\n\n- `Linux >= 07343110b293456d30393e89b86c4dee1ac051c8 < 2f8c69a72e8ad87b36b8052f789da3cc2b2e186c`\n- `Linux >= 07343110b293456d30393e89b86c4dee1ac051c8 < 7bf4461f1c97207fda757014690d55a447ce859f`\n- `Linux >= 07343110b293456d30393e89b86c4dee1ac051c8 < 2d834477bbc1e8b8a59ff8b0c081529d6bed7b22`\n- `Linux >= 07343110b293456d30393e89b86c4dee1ac051c8 < b522d4d334f206284b1a44b0b0b2f99fd443b39b`\n- `Linux >= 07343110b293456d30393e89b86c4dee1ac051c8 < d4965578267e2e81f67c86e2608481e77e9c8569`\n- `Linux 5.19`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
