About this tag
The usb c security archive covers a series of Linux kernel vulnerabilities affecting USB Type-C Power Delivery, UCSI connector management, DisplayPort Alternate Mode, and controller firmware updates. Recent reports examine malformed or malicious devices, cables, docks, chargers, firmware files, and protocol messages that can trigger memory disclosure, memory corruption, invalid memory access, or kernel crashes. The coverage emphasizes how USB-C ports depend on firmware, embedded controllers, and low-level operating-system drivers rather than acting as simple peripheral connections. It also highlights patching updated Linux kernel releases and the relevance to Windows users running Linux through WSL, dual-boot setups, or enterprise fleet-management environments.

    CVE-2026-63964: Fix Linux USB-C Firmware Update Kernel Crashes

    CVE-2026-63964 is a narrowly scoped but technically important Linux kernel flaw in the Cypress CCGx USB Type-C controller driver: a malformed firmware file that contains no colon-delimited record header can push the kernel into an invalid memory-access path during a controller firmware update...

    CVE-2026-63958: Update Linux Kernel to Fix USB-C UCSI Memory Bug

    CVE-2026-63958 is a newly cataloged Linux kernel vulnerability in the USB Type-C Connector System Software Interface, or UCSI, code that deserves attention well beyond the usual Linux security mailing lists: a malformed connector-change notification from firmware or a USB-C controller can cause...
