{"id":"CVE-2023-53470","summary":"ionic: catch failure from devlink_alloc","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nionic: catch failure from devlink_alloc\n\nAdd a check for NULL on the alloc return.  If devlink_alloc() fails and\nwe try to use devlink_priv() on the NULL return, the kernel gets very\nunhappy and panics. With this fix, the driver load will still fail,\nbut at least it won't panic the kernel.","modified":"2026-04-02T09:44:16.317120Z","published":"2025-10-01T11:42:40.221Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53470.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0020c16c8af7f4bc9503a2088fb30793b6771fac"},{"type":"WEB","url":"https://git.kernel.org/stable/c/0d02efe7f25158c93146e3bb827bc7bb3cd5e71a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4a54903ff68ddb33b6463c94b4eb37fc584ef760"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5325f50de5b1433b27dda7ccff5cb7283722a3f1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c177dd465f5c1e5f242cdb9258826c591c257e9a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53470.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53470"},{"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":"df69ba43217d3cf4215c83c0627ce98a26e56e7c"},{"fixed":"c177dd465f5c1e5f242cdb9258826c591c257e9a"},{"fixed":"0d02efe7f25158c93146e3bb827bc7bb3cd5e71a"},{"fixed":"5325f50de5b1433b27dda7ccff5cb7283722a3f1"},{"fixed":"0020c16c8af7f4bc9503a2088fb30793b6771fac"},{"fixed":"4a54903ff68ddb33b6463c94b4eb37fc584ef760"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-53470.json"}}],"schema_version":"1.7.5"}
