If an interrupt has already occurred then waiting for  \nthe interrupt handler to complete will deadlock because it will be trying  \nto acquire the same mutex.  \n  \nCPU0                           CPU1  \n----                           ----  \nmcp251x_open()  \n mutex_lock(&priv->mcp_lock)  \n  request_threaded_irq()  \n                                 \n                               mcp251x_can_ist()  \n                                mutex_lock(&priv->mcp_lock)  \n  mcp251x_hw_wake()  \n   disable_irq() <--\nSeverity: 0.0 | NA \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n  \"Detection Date\": \"18 Sep 2024\",\n  \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "creation_timestamp": "2024-09-18T10:52:37.000000Z"}, {"uuid": "0401622a-e464-43d5-9337-6201aa4cc771", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "2a075640-a300-48a4-bb44-bc6130783b9b", "vulnerability": "CVE-2024-46791", "type": "seen", "source": "https://www.cisa.gov/news-events/ics-advisories/icsa-25-226-07", "content": "", "creation_timestamp": "2025-08-14T10:00:00.000000Z"}]}
