  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nscsi: sd: fix missing put_disk() when device_add(&disk_dev) fails\nIf device_add(&sdkp->disk_dev) fails, put_device() runs\nscsi_disk_release(), which frees the scsi_disk but leaves the gendisk\nreferenced. The device_add_disk() error path in sd_probe() calls\nput_disk(gd); call put_disk(gd) here to mirror that cleanup.", "A flaw was found in the Linux kernel's SCSI disk (sd) driver. When adding a new device, a failure in `device_add()` can lead to a resource leak where a gendisk remains referenced but is not properly freed. This missing cleanup, specifically the `put_disk()` call, can result in resource exhaustion. A local attacker could potentially exploit this to cause a Denial of Service (DoS) on the system." ],
