{"id":"CVE-2024-35961","summary":"net/mlx5: Register devlink first under devlink lock","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet/mlx5: Register devlink first under devlink lock\n\nIn case device is having a non fatal FW error during probe, the\ndriver will report the error to user via devlink. This will trigger\na WARN_ON, since mlx5 is calling devlink_register() last.\nIn order to avoid the WARN_ON[1], change mlx5 to invoke devl_register()\nfirst under devlink lock.\n\n[1]\nWARNING: CPU: 5 PID: 227 at net/devlink/health.c:483 devlink_recover_notify.constprop.0+0xb8/0xc0\nCPU: 5 PID: 227 Comm: kworker/u16:3 Not tainted 6.4.0-rc5_for_upstream_min_debug_2023_06_12_12_38 #1\nHardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014\nWorkqueue: mlx5_health0000:08:00.0 mlx5_fw_reporter_err_work [mlx5_core]\nRIP: 0010:devlink_recover_notify.constprop.0+0xb8/0xc0\nCall Trace:\n \u003cTASK\u003e\n ? __warn+0x79/0x120\n ? devlink_recover_notify.constprop.0+0xb8/0xc0\n ? report_bug+0x17c/0x190\n ? handle_bug+0x3c/0x60\n ? exc_invalid_op+0x14/0x70\n ? asm_exc_invalid_op+0x16/0x20\n ? devlink_recover_notify.constprop.0+0xb8/0xc0\n devlink_health_report+0x4a/0x1c0\n mlx5_fw_reporter_err_work+0xa4/0xd0 [mlx5_core]\n process_one_work+0x1bb/0x3c0\n ? process_one_work+0x3c0/0x3c0\n worker_thread+0x4d/0x3c0\n ? process_one_work+0x3c0/0x3c0\n kthread+0xc6/0xf0\n ? kthread_complete_and_exit+0x20/0x20\n ret_from_fork+0x1f/0x30\n \u003c/TASK\u003e","modified":"2026-03-20T12:36:45.930137Z","published":"2024-05-20T09:41:52.551Z","related":["SUSE-SU-2024:2135-1","SUSE-SU-2024:2203-1","SUSE-SU-2024:2894-1","SUSE-SU-2024:2939-1","SUSE-SU-2024:2947-1","SUSE-SU-2024:2973-1","SUSE-SU-2025:20008-1","SUSE-SU-2025:20028-1","SUSE-SU-2025:20166-1","SUSE-SU-2025:20249-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/35xxx/CVE-2024-35961.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/8c91c60858473731bcdaf04fda99fcbcf84420d4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/967caa3d37c078e5b95a32094657e6a4cad145f0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c6e77aa9dd82bc18a89bf49418f8f7e961cfccc8"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/35xxx/CVE-2024-35961.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-35961"},{"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":"cf530217408e3686f7002429769ede59dd931151"},{"fixed":"8c91c60858473731bcdaf04fda99fcbcf84420d4"},{"fixed":"967caa3d37c078e5b95a32094657e6a4cad145f0"},{"fixed":"c6e77aa9dd82bc18a89bf49418f8f7e961cfccc8"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-35961.json"}}],"schema_version":"1.7.5"}
