CVE-2026-64014

Kernel-memory disclosure via oversized NEXIO packet lengths

Published Jul 19, 2026 · Updated Jul 19, 2026

Out-of-bounds read in Linux Kernel's NEXIO USB touchscreen driver allows physically proximate attackers to disclose kernel memory. nexio_read_data() trusts 16-bit data_len and x_len packet fields and can scan about 64 KiB beyond its 1,017-byte data array. A malicious NEXIO-class USB device must be attached; leaked bytes reach userspace as touch coordinates, and farther reads can fault and crash the host.
