-
In the Linux kernel, the following vulnerability has been resolved:
igc: avoid kernel warning when changing RX ring parameters
Calling ethtool changing the RX ring parameters like this:
$ ethtool -G eth0 rx 1024
on igc triggers kernel warnings like this:

igcethtoolsetringparam() copies the igcring structure but neglects to reset the xdprxqinfo member before calling igcsetuprxresources(). This in turn calls xdprxqinforeg() with an already registered xdprxqinfo.
Make sure to unregister the xdprxqinfo structure first in igcsetuprx_resources.
