Summary
In the Linux kernel, the following vulnerability has been resolved: HID: core: ensure the allocated report buffer can contain the reserved report ID When the report ID is not used, the low level transport drivers expect the first byte to be 0. However, currently the allocated buffer not account for that extra byte, meaning that instead of having 8 guaranteed bytes for implement to be working, we only have 7.
