Description OSIDB Bzimport 2026-01-31 12:01:50 UTC 
In the Linux kernel, the following vulnerability has been resolved:

gpio: mpsse: fix reference leak in gpio_mpsse_probe() error paths

The reference obtained by calling usb_get_dev() is not released in the
gpio_mpsse_probe() error paths. Fix that by using device managed helper
functions. Also remove the usb_put_dev() call in the disconnect function
since now it will be released automatically.
