{"id":"CVE-2025-37812","summary":"usb: cdns3: Fix deadlock when using NCM gadget","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nusb: cdns3: Fix deadlock when using NCM gadget\n\nThe cdns3 driver has the same NCM deadlock as fixed in cdnsp by commit\n58f2fcb3a845 (\"usb: cdnsp: Fix deadlock issue during using NCM gadget\").\n\nUnder PREEMPT_RT the deadlock can be readily triggered by heavy network\ntraffic, for example using \"iperf --bidir\" over NCM ethernet link.\n\nThe deadlock occurs because the threaded interrupt handler gets\npreempted by a softirq, but both are protected by the same spinlock.\nPrevent deadlock by disabling softirq during threaded irq handler.","modified":"2026-04-16T04:40:20.487907032Z","published":"2025-05-08T06:26:09.355Z","related":["SUSE-SU-2025:01964-1","SUSE-SU-2025:01965-1","SUSE-SU-2025:02000-1","SUSE-SU-2025:02254-1","SUSE-SU-2025:02307-1","SUSE-SU-2025:02333-1","SUSE-SU-2025:02923-1","SUSE-SU-2025:20408-1","SUSE-SU-2025:20413-1","SUSE-SU-2025:20419-1","SUSE-SU-2025:20421-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/37xxx/CVE-2025-37812.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/09e90a9689a4aac7a2f726dc2aa472b0b37937b7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/48a62deb857f0694f611949015e70ad194d97159"},{"type":"WEB","url":"https://git.kernel.org/stable/c/59a760e4796a3cd88d8b9d7706e0a638de677751"},{"type":"WEB","url":"https://git.kernel.org/stable/c/74cd6e408a4c010e404832f0e4609d29bf1d0c41"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a1059896f2bfdcebcdc7153c3be2307ea319501f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b96239582531775f2fdcb14de29bdb6870fd4c8c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c27db84ed44e50ff90d9e3a2a25fae2e0a0fa015"},{"type":"WEB","url":"https://git.kernel.org/stable/c/eebfb64c624fc738b669100173344fb441c5e719"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/05/msg00030.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/05/msg00045.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/37xxx/CVE-2025-37812.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-37812"},{"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":"7733f6c32e36ff9d7adadf40001039bf219b1cbe"},{"fixed":"eebfb64c624fc738b669100173344fb441c5e719"},{"fixed":"59a760e4796a3cd88d8b9d7706e0a638de677751"},{"fixed":"b96239582531775f2fdcb14de29bdb6870fd4c8c"},{"fixed":"c27db84ed44e50ff90d9e3a2a25fae2e0a0fa015"},{"fixed":"48a62deb857f0694f611949015e70ad194d97159"},{"fixed":"74cd6e408a4c010e404832f0e4609d29bf1d0c41"},{"fixed":"09e90a9689a4aac7a2f726dc2aa472b0b37937b7"},{"fixed":"a1059896f2bfdcebcdc7153c3be2307ea319501f"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-37812.json"}}],"schema_version":"1.7.5"}
