CVE-2026-63898

In the Linux kernel USB serial stack, the mct_u232 driver could override the maximum transfer size for a device that only accepts 16-byte packets on its 32-byte bulk-out endpoint, risking slab corruption if a smaller endpoint max packet size was reported. The vulnerability is addressed by ensurin...
