CVE-2026-90268
scsi: sd: Fix error handling in sd_probe() after large pool creation failure
Description
In the Linux kernel, the following vulnerability has been resolved: scsi: sd: Fix error handling in sd_probe() after large pool creation failure After device_add(&sdkp->disk_dev) succeeds, sd_large_pool_create() failure must unregister disk_dev and let scsi_disk_release() free sdkp. Going through out_free_index kfree()s an already registered device and leaks the sysfs entry.
