CVE-2026-90337

CVE-2026-90337 is a Linux kernel vulnerability in the serial core . In serial_core_add_one_port(), the uport->tty_groups and uport->name allocations occur after uart_configure_port() registers the console. If an allocation fails, the driver unwinds the port while its console remains registe...

In the Linux kernel, the following vulnerability has been resolved: serial: core: do fallible allocations before the console can be registered serialcoreaddoneport allocates uport-ttygroups after uartconfigureport, which may register the console. If the allocation fails, the driver unwinds the po...

CVE-2026-90336

CVE-2026-90336 affects the Linux kernel serial core subsystem. When uart_register_driver() fails, drv->state is left pointing to freed memory after tty_alloc_driver() fails, and drv->tty_driver retains a dangling pointer after tty_register_driver() fails. Drivers that use drv->state as a...

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...
