NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-source-rt package and not the kernel-source-rt package as distributed by SLES.

A vulnerability was found in the Linux kernel, where accessing a deallocated instance in printer_ioctl() printer_ioctl() tries to access of a printer_dev instance. However, use-after-free arises because it had been freed by gprinter_free().
