CVE-2024-38410

Memory corruption via double-freed WMI command buffer

Published Nov 4, 2024 · Updated Nov 16, 2024

Stack-based buffer overflow in Qualcomm Snapdragon firmware allows local users to corrupt memory through an IOCTL in an invalid device state. The host-side path processes the IOCTL while the device is invalid and can free the WMI command buffer twice, corrupting memory. Low-privileged local access is required; Qualcomm has not disclosed the affected IOCTL, code path, or a more specific consequence than memory corruption.
