In the Linux kernel, the following vulnerability has been resolved:of: module: add buffer overflow check in of_modalias()In of_modalias(), if the buffer happens to be too small even for the 1stsnprintf() call, the len parameter will become negative and str parameter(if not NULL initially) will point beyond the buffer's end. Add the bufferoverflow check after the 1st snprintf() call and fix such check after thestrlen() call (accounting for the terminating NUL char).
CWE-120 Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')
