Description Sandipan Roy 2022-02-17 06:17:23 UTC 
An issue was discovered in the Linux kernel before 5.16.10. The USB Gadget subsystem lacks certain validation of interface OS descriptor requests (ones with a large array index and ones associated with NULL function pointer retrieval). Memory corruption might occur.
