CVE-2026-90335 tty: skip cdev_del() when no cdev is registered

In the Linux kernel, the following vulnerability has been resolved: tty: skip cdevdel 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 cdevdel, causing a...

CVE-2026-90335

CVE-2026-90335 is a NULL-pointer dereference in the Linux kernel's TTY subsystem (serial core). When TTY device registration fails before a cdev is allocated, the serial core retains the port for use by setserial. On later removal, the NULL cdev slot is passed to cdev_del(), triggering the derefe...
