NVD Description

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

In the Linux kernel, the following vulnerability has been resolved:

tty: skip cdev_del() when no cdev is registered

TTY device registration can fail before a cdev is allocated. Serial core keeps the port so setserial can still use it, and later removal passes the NULL cdev slot to cdev_del(), causing a NULL-pointer dereference.

Only delete the cdev when the slot is not NULL.
