CVE-2025-47358

Kernel memory corruption via modified mem_free address

Published Feb 2, 2026 · Updated Feb 2, 2026

Use-after-free in Qualcomm Snapdragon Secure Processor firmware allows local users to corrupt kernel memory through the mem_free API. A user-space address is modified before being passed to mem_free, which then inadvertently frees kernel memory instead of the intended user allocation. Low-privileged local access is required; the resulting corruption can expose or alter protected data and interrupt device operation.
