{"id":"CVE-2026-53233","summary":"netdev: fix double-free in netdev_nl_bind_rx_doit()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnetdev: fix double-free in netdev_nl_bind_rx_doit()\n\nSashiko flags that genlmsg_reply() always consumes the skb.\nThe error path calls nlmsg_free(rsp) so we can't jump directly\nto it. Let's not unbind, just propagate the error to the user.\nThis is the typical way of handling genlmsg_reply() failures.\nThey shouldn't happen unless user does something silly like\ncalling the kernel with an already-full rcvbuf.","modified":"2026-07-17T21:11:42.357398604Z","published":"2026-06-25T08:39:31.191Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53233.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/9b019376cbee10c4f9184d1745fa37d156e36f30"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c299321bc6232770ce378d6fa6bc46004d2d7fdb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c849de7d8757a7af801fc4a4058f71d481d367f2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e055ca9205d3eb6aec3e5fe4ecc18abbbf18c599"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53233.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53233"},{"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":"170aafe35cb98e0f3fbacb446ea86389fbce22ea"},{"fixed":"e055ca9205d3eb6aec3e5fe4ecc18abbbf18c599"},{"fixed":"c299321bc6232770ce378d6fa6bc46004d2d7fdb"},{"fixed":"9b019376cbee10c4f9184d1745fa37d156e36f30"},{"fixed":"c849de7d8757a7af801fc4a4058f71d481d367f2"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-53233.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.12.0"},{"fixed":"6.12.94"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.36"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.13"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-53233.json"}}],"schema_version":"1.7.5"}
