CVE-2026-63898

In the Linux kernel, the following vulnerability has been resolved: USB: serial: mctu232: 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 increas...

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...

In the Linux kernel, the following vulnerability has been resolved: USB: serial: mctu232: fix missing interrupt-in transfer sanity check Add the missing sanity check on the size of interrupt-in transfers to avoid parsing stale or uninitialised slab data and leaking it to user space...

CVE-2026-63897

The CVE-2026-63897 entry concerns the Linux kernel USB serial driver mct_u232. A missing sanity check on the size of interrupt-in transfers could allow parsing of stale or uninitialised slab data, potentially leaking kernel data to user space. The vulnerability is addressed by kernel fixes that a...
