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.
AI Analysis
Technical Summary
The Linux kernel's freescale imx8qm-hsio driver contained a NULL pointer dereference vulnerability (CWE-476) due to the refclk_pad pointer being set to NULL if the 'fsl,refclk-pad-mode' property was not defined in the device tree node. The pointer was then used unconditionally in imx_hsio_configure_clk_pad(), which could cause a kernel crash. The vulnerability has been fixed by adding a check to ensure the pointer is not NULL before use.
Potential Impact
This vulnerability can cause a denial of service (kernel crash) due to a NULL pointer dereference. There is no impact on confidentiality or integrity. The CVSS vector indicates local attack vector with low complexity and low privileges required, no user interaction, and an impact limited to availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
