SUSE CVE-2026-45997

In the Linux kernel, the following vulnerability has been resolved: scsi: sd: fix missing putdisk when deviceadd&diskdev fails If deviceadd&sdkp-diskdev fails, putdevice runs scsidiskrelease, which frees the scsidisk but leaves the gendisk referenced. The deviceadddisk error path in sdprobe calls...
