CVE-2026-45874

About vulnerability

In the Linux kernel, the following vulnerability has been resolved: phy: freescale: imx8qm-hsio: fix NULL pointer dereference During the probe the refclk_pad pointer is set to NULL if the ‘fsl,refclk-pad-mode’ property is not defined in the devicetree node. But in imx_hsio_configure_clk_pad() this pointer is unconditionally used which could result in a NULL pointer dereference. So check the pointer before to use it. A flaw was found in the Linux kernel, within the phy: freescale: imx8qm-hsio component. This vulnerability occurs when a specific pointer, refclk_pad, is not properly initialized and is later used without validation. This can lead to a NULL pointer dereference, which may cause the system to crash. Such a crash results in a Denial of Service (DoS), making the affected system unavailable.
