Last modified

CVE-2026-90335 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.21% chance of exploitation in the next 30 days.
