{"id":"CVE-2025-37933","summary":"octeon_ep: Fix host hang issue during device reboot","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nocteon_ep: Fix host hang issue during device reboot\n\nWhen the host loses heartbeat messages from the device,\nthe driver calls the device-specific ndo_stop function,\nwhich frees the resources. If the driver is unloaded in\nthis scenario, it calls ndo_stop again, attempting to free\nresources that have already been freed, leading to a host\nhang issue. To resolve this, dev_close should be called\ninstead of the device-specific stop function.dev_close\ninternally calls ndo_stop to stop the network interface\nand performs additional cleanup tasks. During the driver\nunload process, if the device is already down, ndo_stop\nis not called.","modified":"2026-03-20T12:42:34.344445Z","published":"2025-05-20T15:21:58.169Z","related":["MGASA-2025-0182","MGASA-2025-0183","SUSE-SU-2025:02249-1","SUSE-SU-2025:02254-1","SUSE-SU-2025:02307-1","SUSE-SU-2025:02333-1","SUSE-SU-2025:02335-1","SUSE-SU-2025:02538-1","SUSE-SU-2025:02923-1","SUSE-SU-2025:20413-1","SUSE-SU-2025:20421-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/37xxx/CVE-2025-37933.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/34f42736b325287a7b2ce37e415838f539767bda"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6d1052423518e7d0aece9af5e77bbc324face8f1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7e1ca1bed3f66e00377f7d2147be390144924276"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c8d788f800f83b94d9db8b3dacc1d26be38a6ef4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/37xxx/CVE-2025-37933.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-37933"},{"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":"5cb96c29aa0ea359e4f5d30585538dc6a847d69d"},{"fixed":"7e1ca1bed3f66e00377f7d2147be390144924276"},{"fixed":"c8d788f800f83b94d9db8b3dacc1d26be38a6ef4"},{"fixed":"6d1052423518e7d0aece9af5e77bbc324face8f1"},{"fixed":"34f42736b325287a7b2ce37e415838f539767bda"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-37933.json"}}],"schema_version":"1.7.5"}
