{"id":"CVE-2024-38567","summary":"wifi: carl9170: add a proper sanity check for endpoints","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: carl9170: add a proper sanity check for endpoints\n\nSyzkaller reports [1] hitting a warning which is caused by presence\nof a wrong endpoint type at the URB sumbitting stage. While there\nwas a check for a specific 4th endpoint, since it can switch types\nbetween bulk and interrupt, other endpoints are trusted implicitly.\nSimilar warning is triggered in a couple of other syzbot issues [2].\n\nFix the issue by doing a comprehensive check of all endpoints\ntaking into account difference between high- and full-speed\nconfiguration.\n\n[1] Syzkaller report:\n...\nWARNING: CPU: 0 PID: 4721 at drivers/usb/core/urb.c:504 usb_submit_urb+0xed6/0x1880 drivers/usb/core/urb.c:504\n...\nCall Trace:\n \u003cTASK\u003e\n carl9170_usb_send_rx_irq_urb+0x273/0x340 drivers/net/wireless/ath/carl9170/usb.c:504\n carl9170_usb_init_device drivers/net/wireless/ath/carl9170/usb.c:939 [inline]\n carl9170_usb_firmware_finish drivers/net/wireless/ath/carl9170/usb.c:999 [inline]\n carl9170_usb_firmware_step2+0x175/0x240 drivers/net/wireless/ath/carl9170/usb.c:1028\n request_firmware_work_func+0x130/0x240 drivers/base/firmware_loader/main.c:1107\n process_one_work+0x9bf/0x1710 kernel/workqueue.c:2289\n worker_thread+0x669/0x1090 kernel/workqueue.c:2436\n kthread+0x2e8/0x3a0 kernel/kthread.c:376\n ret_from_fork+0x1f/0x30 arch/x86/entry/entry_64.S:308\n \u003c/TASK\u003e\n\n[2] Related syzkaller crashes:","modified":"2026-03-20T12:37:08.076205Z","published":"2024-06-19T13:35:34.254Z","related":["MGASA-2024-0263","MGASA-2024-0266","SUSE-SU-2024:2360-1","SUSE-SU-2024:2372-1","SUSE-SU-2024:2381-1","SUSE-SU-2024:2394-1","SUSE-SU-2024:2561-1","SUSE-SU-2024:2571-1","SUSE-SU-2024:2896-1","SUSE-SU-2024:2939-1","SUSE-SU-2024:2973-1","SUSE-SU-2025:20008-1","SUSE-SU-2025:20028-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/38xxx/CVE-2024-38567.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/03ddc74bdfd71b84a55c9f2185d8787f258422cd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0fa08a55201ab9be72bacb8ea93cf752d338184f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/265c3cda471c26e0f25d0c755da94e1eb15d7a0c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/62eb07923f3693d55b0c2d9a5a4f1ad72cb6b8fd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6a9892bf24c906b4d6b587f8759ca38bff672582"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8650725bb0a48b206d5a8ddad3a7488f9a5985b7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ac3ed46a8741d464bc70ebdf7433c1d786cf329d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b6dd09b3dac89b45d1ea3e3bd035a3859c0369a0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/eb0f2fc3ff5806cc572cd9055ce7c52a01e97645"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/06/msg00020.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/38xxx/CVE-2024-38567.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-38567"},{"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":"a84fab3cbfdc427e7d366f1cc844f27b2084c26c"},{"fixed":"eb0f2fc3ff5806cc572cd9055ce7c52a01e97645"},{"fixed":"ac3ed46a8741d464bc70ebdf7433c1d786cf329d"},{"fixed":"8650725bb0a48b206d5a8ddad3a7488f9a5985b7"},{"fixed":"6a9892bf24c906b4d6b587f8759ca38bff672582"},{"fixed":"265c3cda471c26e0f25d0c755da94e1eb15d7a0c"},{"fixed":"62eb07923f3693d55b0c2d9a5a4f1ad72cb6b8fd"},{"fixed":"03ddc74bdfd71b84a55c9f2185d8787f258422cd"},{"fixed":"0fa08a55201ab9be72bacb8ea93cf752d338184f"},{"fixed":"b6dd09b3dac89b45d1ea3e3bd035a3859c0369a0"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-38567.json"}}],"schema_version":"1.7.5"}
