CVE-2024-46869

Kernel memory corruption via missing driver allocation

Published Sep 30, 2024 · Updated Aug 5, 2026

Memory corruption in Linux 6.10 before 6.10.12 and 6.11 before 6.11.1 allows local users to crash the kernel during Bluetooth setup. The btintel_pcie probe path allocates hci_dev without reserving struct btintel_data, so later flag and pointer accesses run beyond that object. Reachability requires an Intel PCIe Bluetooth controller and local access to bring up or exercise its HCI device; corruption can panic the host or alter adjacent kernel objects.
