CVE-2026-43250

A flaw was found in the Linux kernel's ChipIdea USB Device Controller (UDC) driver. A local user with a malicious USB device, or a malicious USB device itself, could exploit this by reconnecting the device during an active data transfer. This improper cleanup of Direct Memory Access (DMA) buffers can lead to the reuse of stale DMA states. Consequently, this can result in memory corruption, potentially causing system instability, crashes, or even arbitrary code execution.
