{"id":"CVE-2026-68321","summary":"net: txgbe: fix FDIR filter leak on remove","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: txgbe: fix FDIR filter leak on remove\n\nPerfect FDIR filters can be added while the interface is down and are\nkept on the software list for later restore. unregister_netdev() only\ncalls ndo_stop when the device is up, so txgbe_fdir_filter_exit() in\ntxgbe_close() is skipped in that case and the filters are leaked on\ndriver remove. Free the filter list from txgbe_remove() as well.","modified":"2026-08-18T03:30:48.737628801Z","published":"2026-08-10T12:02:56.166Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68321.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2d34421bfa261f7e83bea2f2f75fa75e0c3037d1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4946dea2386333e5d93bfb36df803fefb5a8c635"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5c2f04258be2645cdd8f87553990948e7054e7fb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ecaa37826340520664a4e5522f803ff48fc3f564"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68321.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68321"},{"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":"4bdb441105dcea40ac6e01756314c0fdf5173ce1"},{"fixed":"5c2f04258be2645cdd8f87553990948e7054e7fb"},{"fixed":"2d34421bfa261f7e83bea2f2f75fa75e0c3037d1"},{"fixed":"4946dea2386333e5d93bfb36df803fefb5a8c635"},{"fixed":"ecaa37826340520664a4e5522f803ff48fc3f564"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-68321.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.11.0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-68321.json"}}],"schema_version":"1.9.0"}
