CVE-2024-35851

Kernel crash via non-serdev suspend NULL dereference

Published May 17, 2024 · Updated May 11, 2026

NULL-pointer dereference in affected Linux kernels allows local users to crash the kernel during suspend on configured systems. In drivers/bluetooth/hci_qca.c, the wakeup callback dereferences the HCI UART serdev pointer without checking whether a Qualcomm ROME controller was registered through the Bluetooth line discipline, which leaves that pointer null. The path is limited to that non-serdev controller registration, and reaching it requires local access to initiate system suspend; the resulting impact is a kernel crash.
