Description OSIDB Bzimport 2026-08-10 12:38:23 UTC
In the Linux kernel, the following vulnerability has been resolved:

usb: core: sysfs: add lock to bos_descriptors_read()

Add a lock to the function bos_descriptors_read().

This function accesses udev->bos, which could be simultaneously freed in
usb_reset_and_verify_device(), a function that is commonly called in
drivers all over the kernel.
