{"id":"CVE-2026-68333","summary":"dpaa2-switch: put MAC endpoint device on disconnect","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndpaa2-switch: put MAC endpoint device on disconnect\n\nfsl_mc_get_endpoint() returns the MAC endpoint device with a reference\ntaken through device_find_child(). The switch port connect path stores\nthat device in mac-\u003emc_dev and keeps it for the lifetime of the connected\nMAC object.\n\nHowever, the disconnect path only closes the MAC and frees the dpaa2_mac\nobject. It does not drop the endpoint device reference stored in\nmac-\u003emc_dev, so every successful connect leaks that device reference when\nthe MAC is later disconnected.\n\nDrop the endpoint device reference before freeing the dpaa2_mac object.","modified":"2026-08-21T03:30:34.261182102Z","published":"2026-08-10T12:03:09.524Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68333.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0e9a6811eb6198ab17538cd01fa155d133b238ed"},{"type":"WEB","url":"https://git.kernel.org/stable/c/196f7301537814bef0f5915f87cd73d6d1235c19"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1f4ca61b7a93de3dfa5161bcd38ecb99bb091c38"},{"type":"WEB","url":"https://git.kernel.org/stable/c/26ac2d3602347f0377fbcd5214bc28a9d735ae68"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4c1eabbef7a1707635652e956e39db1269c3af2b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/680eecc850d36a280df9780496bc603fec17b2d6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c27694ff6748e08fcd2fdba89018439d75b8198f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68333.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68333"},{"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":"84cba72956fddf29ba666f885c39ed147024c125"},{"fixed":"196f7301537814bef0f5915f87cd73d6d1235c19"},{"fixed":"0e9a6811eb6198ab17538cd01fa155d133b238ed"},{"fixed":"1f4ca61b7a93de3dfa5161bcd38ecb99bb091c38"},{"fixed":"680eecc850d36a280df9780496bc603fec17b2d6"},{"fixed":"26ac2d3602347f0377fbcd5214bc28a9d735ae68"},{"fixed":"c27694ff6748e08fcd2fdba89018439d75b8198f"},{"fixed":"4c1eabbef7a1707635652e956e39db1269c3af2b"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-68333.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.15.0"},{"fixed":"5.15.216"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.183"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.148"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"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-2026-68333.json"}}],"schema_version":"1.9.0"}
