CVE-2026-63898
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
which only accepts 16 byte packets for its 32 byte bulk-out endpoint.
Make sure to never increase the maximum transfer size to prevent slab
corruption should a malicious device report a smaller endpoint max
packet size than expected.
