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...

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...

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-2026-90297

CVE-2026-90297 is a null pointer dereference (kernel oops) in the Linux kernel's drm/sun4i driver (Allwinner). The function sun4i_crtc_init() returns plain NULL when layer initialization fails, while its other error paths return an error pointer. Its sole caller, sun4i_tcon_bind(), checks the res...

CVE-2026-90293

CVE-2026-90293 is a NULL pointer dereference in the Linux kernel's IB/isert (iSCSI target over RDMA) component. The function isert_put_login_tx() posts full-feature receive buffers before __transport_register_session() completes, so an iSCSI initiator that sends a SCSI command before receiving th...

CVE-2026-90294

CVE-2026-90294 is a NULL pointer dereference in the Linux kernel's iSCSI over RDMA target (iSER) module. The root cause is a race condition: isert_put_login_tx() transmits the final Login Response before __transport_register_session() completes, so an initiator that immediately issues a SCSI comm...
