{"id":"CVE-2023-53013","summary":"ptdma: pt_core_execute_cmd() should use spinlock","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nptdma: pt_core_execute_cmd() should use spinlock\n\nThe interrupt handler (pt_core_irq_handler()) of the ptdma\ndriver can be called from interrupt context. The code flow\nin this function can lead down to pt_core_execute_cmd() which\nwill attempt to grab a mutex, which is not appropriate in\ninterrupt context and ultimately leads to a kernel panic.\nThe fix here changes this mutex to a spinlock, which has\nbeen verified to resolve the issue.","modified":"2026-04-02T09:43:33.495651Z","published":"2025-03-27T16:43:42.437Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53013.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/13ba563c2c8055ba8a637c9f70bb833b43cb4207"},{"type":"WEB","url":"https://git.kernel.org/stable/c/95e5fda3b5f9ed8239b145da3fa01e641cf5d53c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ed0d8f731e0bf1bb12a7a37698ac613db20e2794"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53013.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53013"},{"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":"fa5d823b16a9442d609617abeec31da8b6afa224"},{"fixed":"ed0d8f731e0bf1bb12a7a37698ac613db20e2794"},{"fixed":"13ba563c2c8055ba8a637c9f70bb833b43cb4207"},{"fixed":"95e5fda3b5f9ed8239b145da3fa01e641cf5d53c"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-53013.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
