CVE-2026-97480

A flaw was found in the Linux kernel's 8250 serial driver. During serial port registration for devices lacking an associated parent device, the driver attempts to access device properties without verifying that the device pointer is valid. This condition leads to a NULL pointer dereference, which...

kernel: USB: serial: io_ti: fix heap overflow in get_manuf_info()

A flaw was found in the Linux kernel's ioti USB serial driver. A malicious USB device, when plugged into a host running this driver, can exploit a heap overflow vulnerability in the getmanufinfo function. This occurs because the driver does not properly validate the size of data read from the...
