Description
In the Linux kernel, the following vulnerability has been resolved:
USB: serial: mct_u232: fix memory corruption with small endpoint
The driver overrides the maximum transfer size for a specific device

corruption should a malicious device report a smaller endpoint max
packet size than expected.
