{"id":"CVE-2025-40107","summary":"can: hi311x: fix null pointer dereference when resuming from sleep before interface was enabled","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ncan: hi311x: fix null pointer dereference when resuming from sleep before interface was enabled\n\nThis issue is similar to the vulnerability in the `mcp251x` driver,\nwhich was fixed in commit 03c427147b2d (\"can: mcp251x: fix resume from\nsleep before interface was brought up\").\n\nIn the `hi311x` driver, when the device resumes from sleep, the driver\nschedules `priv-\u003erestart_work`. However, if the network interface was\nnot previously enabled, the `priv-\u003ewq` (workqueue) is not allocated and\ninitialized, leading to a null pointer dereference.\n\nTo fix this, we move the allocation and initialization of the workqueue\nfrom the `hi3110_open` function to the `hi3110_can_probe` function.\nThis ensures that the workqueue is properly initialized before it is\nused during device resume. And added logic to destroy the workqueue\nin the error handling paths of `hi3110_can_probe` and in the\n`hi3110_can_remove` function to prevent resource leaks.","modified":"2026-04-16T04:31:27.941082333Z","published":"2025-11-03T12:15:12.587Z","related":["SUSE-SU-2025:4393-1","SUSE-SU-2025:4422-1","SUSE-SU-2025:4505-1","SUSE-SU-2025:4516-1","SUSE-SU-2025:4517-1","SUSE-SU-2025:4521-1","SUSE-SU-2026:20012-1","SUSE-SU-2026:20015-1","SUSE-SU-2026:20021-1","SUSE-SU-2026:20039-1","SUSE-SU-2026:20059-1","SUSE-SU-2026:20473-1","SUSE-SU-2026:20496-1","openSUSE-SU-2025:20172-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/40xxx/CVE-2025-40107.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1d2ef21f02baff0c109ad78b9e835fb4acb14533"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6b696808472197b77b888f50bc789a3bae077743"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d1fc4c041459e2d4856c1b2501486ba4f0cbf96b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e93af787187e585933570563c643337fa731584a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fd00cf38fd437c979f0e5905e3ebdfc3f55a4b96"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/40xxx/CVE-2025-40107.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-40107"},{"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":"57e83fb9b7468c75cb65cde1d23043553c346c6d"},{"fixed":"d1fc4c041459e2d4856c1b2501486ba4f0cbf96b"},{"fixed":"e93af787187e585933570563c643337fa731584a"},{"fixed":"1d2ef21f02baff0c109ad78b9e835fb4acb14533"},{"fixed":"fd00cf38fd437c979f0e5905e3ebdfc3f55a4b96"},{"fixed":"6b696808472197b77b888f50bc789a3bae077743"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-40107.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.12.0"},{"fixed":"6.1.156"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.111"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.16.12"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-40107.json"}}],"schema_version":"1.7.5"}
