Summary

In the Linux kernel, the following vulnerability has been resolved:

HID: steam: Reject short reads

Steam Controller FEATURE reports encode the size of the message in the message itself. Previously we were trusting that the size reported matched the size we actually read, leading to a potential issue with short reads. Instead, we should actually verify the length of the read.
