Summary
In the Linux kernel, the following vulnerability has been resolved: net: atlantic: fix aq_vec index out of range error The final update statement of the for loop exceeds the array range, the dereference of self->aq_vec[i] is not checked and then leads to the index out of range error. Also fixed this kind of coding style in other for loop.
