Recommended response

Check inventory. Check lockfiles and deployed manifests for Linux/Linux, Linux/Linux, Linux/Linux.
Review the reported fix. Update Linux/Linux to c07caee449c968842a350bfefa049889923b8240; Linux/Linux to c07caee449c968842a350bfefa049889923b8240 if you use the affected versions. Test the change in a non-production environment first.

Sources and claim methodology

Upstream source description

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.
