linux / linux_kernel
Description
In the Linux kernel, the following vulnerability has been resolved:
net: libwx: remove duplicate page_pool_put_full_page()
page_pool_put_full_page() 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:
