CVE-2026-31620 ALSA: usx2y: us144mkii: fix NULL deref on missing interface 0

In the Linux kernel, the following vulnerability has been resolved: ALSA: usx2y: us144mkii: fix NULL deref on missing interface 0 A malicious USB device with the TASCAM US-144MKII device id can have a configuration containing bInterfaceNumber=1 but no interface 0. USB configuration descriptors ar...

CVE-2026-31620

CVE-2026-31620 affects the Linux kernel ALSA usx2y driver (TASCAM US-144MKII). A malicious USB device can present a configuration with bInterfaceNumber=1 but no interface 0, causing usb_ifnum_to_if(dev,0) to dereference NULL. This can crash the kernel (DoS). The fix is to properly check the retur...
