Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
net: mvneta: fix calls to page_pool_get_stats
Calling page_pool_get_stats in the mvneta driver without checks leads to kernel crashes. First the page pool is only available if the bm is not used. The page pool is also not allocated when the port is stopped. It can also be not allocated in case of errors.
The current implementation leads to the following crash calling ethstats on a port that is down or when calling it at the wrong moment:
