CVE-2024-45006

Kernel crash via uninitialized xHCI bandwidth table pointers

Published Sep 4, 2024 · Updated May 11, 2026

NULL pointer dereference in Linux kernel xHCI support from 4.15 allows local users to crash the kernel during full-speed USB re-enumeration. After an address-device command fails, slot re-enablement allocates an xhci_virt_device without initializing its bandwidth-table pointers; xhci_reserve_bandwidth later dereferences them. Exploitation requires Panther Point xHCI hardware, a failed address-device command, and subsequent endpoint-zero reconfiguration.
