Description
A flaw was found in the Linux kernel's ice driver. A local user could trigger a resource leak by resetting all Virtual Functions (VFs) while FDIR (Flow Director) filters are enabled. This occurs because control VSIs (Virtual Station Interfaces) are invalidated but not properly freed, leading to a gradual consumption of system resources. This resource exhaustion can ultimately result in a Denial of Service (DoS) for the affected system.
