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.
