UBUNTU-CVE-2026-90335

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...
