CVE-2025-38301

Estado: AnalizadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

nvmem: zynqmp_nvmem: unbreak driver after cleanup

Commit 29be47fcd6a0 ("nvmem: zynqmp_nvmem: zynqmp_nvmem_probe cleanup") changed the driver to expect the device pointer to be passed as the "context", but in nvmem the context parameter comes from nvmem_config.priv which is never set - Leading to null pointer exceptions when the device is accessed.
