{"id":"CVE-2026-64242","summary":"usb: gadget: net2280: Fix double free in probe error path","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nusb: gadget: net2280: Fix double free in probe error path\n\nusb_initialize_gadget() installs gadget_release() as the release\ncallback for the embedded gadget device.  The struct net2280 instance is\ntherefore released through gadget_release() when the gadget device's last\nreference is dropped.\n\nThe probe error path calls net2280_remove(), which tears down the\npartially initialized device and drops the gadget reference with\nusb_put_gadget().  Calling kfree(dev) afterwards can free the same object\nagain.\n\nDrop the explicit kfree() and let the gadget device release callback\nhandle the final free.  This issue was found by a static analysis tool\nI am developing.","modified":"2026-07-27T04:03:19.810291180Z","published":"2026-07-24T15:27:44.730Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64242.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/085652fda7f38040d1a2c42d72614f418feb843f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/48f89ead20e48d447ad29fa937b43b9fa981cf28"},{"type":"WEB","url":"https://git.kernel.org/stable/c/550fa4d071a8c8e53072900869d37ae6abf4999d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/71b3391dc81655ff058492f8e9d013b2c6e5747b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c5b9fdb1e8ddf50bc6272927edb118679f170350"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c8547c74988e0b5f4cbb1b895e2a57aae084f070"},{"type":"WEB","url":"https://git.kernel.org/stable/c/db2b72e83a0208ae2b3b270bf91662b1c6849a9b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e6f8be12f0307145b9a6010f044925952b37de8b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64242.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64242"},{"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":"f770fbec4165b1acfabdeadb01ad6008d2c537b5"},{"fixed":"71b3391dc81655ff058492f8e9d013b2c6e5747b"},{"fixed":"550fa4d071a8c8e53072900869d37ae6abf4999d"},{"fixed":"c5b9fdb1e8ddf50bc6272927edb118679f170350"},{"fixed":"085652fda7f38040d1a2c42d72614f418feb843f"},{"fixed":"48f89ead20e48d447ad29fa937b43b9fa981cf28"},{"fixed":"e6f8be12f0307145b9a6010f044925952b37de8b"},{"fixed":"db2b72e83a0208ae2b3b270bf91662b1c6849a9b"},{"fixed":"c8547c74988e0b5f4cbb1b895e2a57aae084f070"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64242.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.10.0"},{"fixed":"5.10.259"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.210"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.176"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.143"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.93"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.35"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.12"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64242.json"}}],"schema_version":"1.7.5"}
