CVE-2026-45997 Details
Description
In the Linux kernel, the following vulnerability has been resolved: scsi: sd: fix missing put_disk() when device_add(&disk_dev) fails If device_add(&sdkp->disk_dev) fails, put_device() runs scsi_disk_release(), which frees the scsi_disk but leaves the gendisk referenced. The device_add_disk() error path in sd_probe() calls put_disk(gd); call put_disk(gd) here to mirror that cleanup.
A vulnerability exists in the Linux kernel's SCSI disk driver, specifically in the sd_probe() function. When the device_add() function fails, the corresponding put_device() call releases the scsi_disk, but the associated gendisk remains referenced, leading to a potential resource leak. The error handling in sd_probe() has been updated to include a call to put_disk() to properly release the gendisk reference, addressing this issue.
Users can upgrade to the latest stable version of the Linux kernel, where this vulnerability has been addressed. Instructions for downloading the latest kernel version can be found on the official Linux kernel website.
