CVE-2025-38016

Kernel memory corruption via post-destroy HID-BPF dispatch

Published Jun 18, 2025 · Updated Aug 5, 2026

Memory corruption in Linux kernels beginning with 6.11 allows physically proximate attackers to corrupt kernel memory via HID teardown. The HID LED worker can run after hid_bpf_destroy_device cleans its SRCU state, and output or raw-request dispatch then locks and updates that destroyed state. Exploitation requires a wireless HID device with active LEDs and a driver lacking request handling; resulting accesses can disclose or corrupt kernel memory and crash the system.
