- Summary
- net: libwx: remove duplicate page_pool_put_full_page()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
net: libwx: remove duplicate pagepoolputfullpage()
pagepoolputfullpage() should only be invoked when freeing Rx buffers or building a skb if the size is too short. At other times, the pages need to be reused. So remove the redundant page put. In the original code, double free pages cause kernel panic:
