CVSS 3.1
4.6 mediumCVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HCVE-2026-31620
Medium (4.6) in linux linux kernel. EPSS 0.2% chance of exploitation in the next 30 days.
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 are not required to assign interface numbers
sequentially, so usb_ifnum_to_if(dev, 0) returns will NULL, which will
then be dereferenced directly.
Fix this up by checking the return value properly.
