(UAF)\n\nIn case of a failure in dibs_dev_add() being called by dibs_lo_dev_probe()\ndmb_clientid_arr is freed twice (double free).\n\nFree dmb_clientid_arr in dibs_dev_release() after last reference is gone.\nNote that allocating in dibs_dev_add() instead of dibs_dev_alloc() is ok\nfor now, because no dmbs can be registered before dibs_dev_add().","published":"2026-08-22T15:32:10.861Z","modified":"2026-08-24T11:47:10.489599053Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"6.18.45"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/7a1df20a8d2cc89e3a442b6e0b43b1cacde8d403"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9e6869be49064915edb6c8776b27c376cfdb0df5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ece6426b61241e9bfb41aa131f235168f55229b1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/74xxx/CVE-2026-74629.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-74629"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-24T11:47:10.489599053Z"}}
