      "value": "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."
