DescriptionNVD

In the Linux kernel, the following vulnerability has been resolved:

bpf, sockmap: Several fixes to bpf_msg_pop_data

Several fixes to bpf_msg_pop_data,

In sk_msg_shift_left, we should put_page
if (len == 0), return early is better
pop the entire sk_msg (last == msg->sg.size) should be supported
Fix for the value of variable "a"
In sk_msg_shift_left, after shifting, i has already pointed to the next

element. Addtional sk_msg_iter_var_next may result in BUG.
