{"id":"CVE-2026-68331","summary":"dpaa2-eth: put MAC endpoint device on disconnect","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndpaa2-eth: 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 Ethernet connect path stores that\ndevice in mac-\u003emc_dev and keeps it for the lifetime of the connected MAC\nobject.\n\nHowever, the disconnect path only disconnects and closes the MAC before\nfreeing the dpaa2_mac object. It does not drop the endpoint device\nreference stored in mac-\u003emc_dev, so every successful connect leaks that\ndevice reference when the MAC is later disconnected.\n\nDrop the endpoint device reference after closing the MAC and before\nfreeing the dpaa2_mac object.","modified":"2026-08-12T04:19:22.648299033Z","published":"2026-08-10T12:03:07.529Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68331.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/915012e923316b8b5d5bf8fc771617b47bd7572d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a3cecf169cc652b558d08661bb6ce55e4c933ec0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b4b201cc93ff70150853aba03e14d314d1980ca0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e23e4a3b9dfd893469c731318d409cdf04fb1ddf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f112df0744e2d77baa68eeebb860021bbaaa022a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/68xxx/CVE-2026-68331.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-68331"},{"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":"71947923089353f23f4f210864903c4dcf2c1696"},{"fixed":"915012e923316b8b5d5bf8fc771617b47bd7572d"},{"fixed":"e23e4a3b9dfd893469c731318d409cdf04fb1ddf"},{"fixed":"f112df0744e2d77baa68eeebb860021bbaaa022a"},{"fixed":"a3cecf169cc652b558d08661bb6ce55e4c933ec0"},{"fixed":"b4b201cc93ff70150853aba03e14d314d1980ca0"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-68331.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.5.0"},{"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/cve-osv-conversion/osv-output/CVE-2026-68331.json"}}],"schema_version":"1.9.0"}
