{"id":"CVE-2026-93070","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-93070","summary":"media: ipu6: Do not free aux device pdata after init","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: ipu6: Do not free aux device pdata after init\n\nipu6_bus_initialize_device() stores the isys/psys pdata pointer in\nstruct ipu6_bus_device and initializes the auxiliary device. After that\npoint, error unwinding must drop the auxiliary device reference and let\nipu6_bus_release() free both the bus device and adev->pdata.\n\nThe isys and psys init paths already call put_device() when MMU\ninitialization fails, and ipu6_bus_add_device() calls\nauxiliary_device_uninit() on auxiliary_device_add() failure. Both paths\ntherefore run the bus release callback. The extra kfree(pdata) in the\ncallers can release the same object a second time.\n\nRemove the manual pdata frees after the auxiliary device has been\ninitialized.\n\nThis issue was found by a static analysis checker and confirmed by\nmanual source review.","published":"2026-09-17T16:10:54.393Z","modified":"2026-09-19T03:47:30.921661424Z","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Linux","name":"Kernel","fixedVersion":"6.12.110"}],"fix":null,"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/5323ed5a7bb2568191ec676b2035b0396105aa05"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7d102d1f0631807a491a140f67c9628dea85dfd2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9be07216af4cfc4813e1a46ce26407d31ea845de"},{"type":"WEB","url":"https://git.kernel.org/stable/c/faa1eb97f0e66bf122f44b62be6b323f86333e9f"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/93xxx/CVE-2026-93070.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-93070"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-19T03:47:30.921661424Z"}}
