CVE-2025-38313

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> bus: fsl-mc: fix double-free on mc_dev<br /> <br /> The blamed commit tried to simplify how the deallocations are done but,<br /> in the process, introduced a double-free on the mc_dev variable.<br /> <br /> In case the MC device is a DPRC, a new mc_bus is allocated and the<br /> mc_dev variable is just a reference to one of its fields. In this<br /> circumstance, on the error path only the mc_bus should be freed.<br /> <br /> This commit introduces back the following checkpatch warning which is a<br /> false-positive.<br /> <br /> WARNING: kfree(NULL) is safe and this check is probably not required<br /> + if (mc_bus)<br /> + kfree(mc_bus);
