CVE-2023-53119

Kernel crash via uninitialized PN533 USB context

Published May 2, 2025 · Updated May 23, 2026

Use of an uninitialized resource in affected Linux kernels allows local users to crash the kernel through PN533 USB error handling. The pn533_out_arg context leaves its phy field uninitialized, and pn533_out_complete() dereferences it while processing an error. Local access to a system using the PN533 USB driver is required; reaching that error path causes a kernel general protection fault.
