CVE-2024-45027

Kernel crash via xHCI cleanup NULL dereference

Published Sep 11, 2024 · Updated May 11, 2026

Incomplete cleanup in Linux 6.8 through 6.10.6 and 6.11-rc1 through 6.11-rc3 allows local users to crash the kernel via xHCI setup failure. When xhci_mem_init() fails after max_interrupters is set but before interrupters is allocated, xhci_mem_cleanup() unconditionally dereferences the NULL interrupters pointer. Low-privileged local access and this early DMA-allocation failure are required; the resulting NULL dereference affects availability only.
