CVE-2024-53046

FlexSPI interruption via incorrect device-tree binding

Published Nov 19, 2024 · Updated May 11, 2026

Availability flaw in affected Linux 6.6–6.12 release-candidate kernels allows local users to interrupt i.MX8ULP FlexSPI access. The imx8ulp.dtsi entry binds the 16-LUT controller to i.MX8MM-compatible data for 32 LUTs, causing nxp_fspi_exec_op to address an unsupported operation slot and raise a kernel warning. Reachability requires an ARM64 NXP i.MX8ULP system using that device tree; the documented consequence is failed FlexSPI operation without confidentiality or integrity impact.
