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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":207363,"id":"CVE-2026-93070","ts":1789757341367,"field":"cvss","old":null,"new":"7.8"},{"seq":207362,"id":"CVE-2026-93070","ts":1789757341367,"field":"severity","old":"none","new":"high"}]}
