CVE-2024-58003

Local kernel compromise via fwnode reference underflow

Published Feb 27, 2025 · Updated Aug 5, 2026

Memory corruption in the ub913 and ub953 media drivers in Linux allows local users to compromise the kernel through repeated driver removal. Each removal calls fwnode_handle_put() on an unowned sd.fwnode reference, so repeated unbind and rebind cycles underflow the reference count and create a use-after-free. Low-privileged local access to driver lifecycle controls is enough to disclose kernel data, hijack control flow, or crash the system.
