there is some memory fault occurred you just check your memory allocation or memset method and its argument also . and study about memory leakage and page fault……
may be you are making the memory area free that is not allocated to your program . thing is that your kfree will work properly and free the memory area specified to it ,but as this memory region wasn’t allocated to your program and u mistakenly freed it thus when the program that was attached to the memory region tries to access it doesn’t find out and kernel got CRAAAASHhh.
Another 1 ,, there can be a problem with ur memset as u r trying to set memory locations that aren’t allocated to you program and after memset performs the setting oprations at unauthorized locations , the program that hv acces to this modified area will found garbeled value and will result into a CRASSShh
