Improper input validation in the Intel(R) Ethernet ixgbe driver for Linux before version 3.17.3 may allow an authenticated user to potentially enable denial of service via local access.
Does this matter?
Lower severity and a low EPSS score (0.31%). Track it; it rarely justifies an emergency change on its own.
