Summary
In the Linux kernel, the following vulnerability has been resolved: kobject_uevent: Fix OOB access within zap_modalias_env() zap_modalias_env() wrongly calculates size of memory block to move, so will cause OOB memory access issue if variable MODALIAS is not the last one within its @env parameter, fixed by correcting size to memmove.
