Description OSIDB Bzimport 2025-09-11 17:01:37 UTC
In the Linux kernel, the following vulnerability has been resolved:

usb: core: config: Prevent OOB read in SS endpoint companion parsing

usb_parse_ss_endpoint_companion() checks descriptor type before length,
enabling a potentially odd read outside of the buffer size.

Fix this up by checking the size first before looking at any of the
fields in the descriptor.
