Fix by using\nice_vf_ctrl_vsi_release() instead of ice_vf_ctrl_invalidate_vsi() which\naligns behavior with the ice_reset_vf() function.\n\nReproduction:\n echo 1 > /sys/class/net/$pf/device/sriov_numvfs\n ethtool -N $vf flow-type ether proto 0x9000 action 0\n echo 1 > /sys/class/net/$pf/device/reset"

"value": "AV:L - The bug is reached via local host interfaces only: VF virtchnl mailbox messages (VIRTCHNL_OP_ADD_FDIR_FILTER) to create per-VF FDIR ctrl VSIs, and PF-wide reset paths (PCI sysfs reset, ethtool-driven PFR/CORER/GLOBR) that call ice_reset_all_vfs(); no network packet receive path is involved.\nAC:L - Once a VF has created an FDIR rule (which allocates the per-VF ctrl VSI), each PF-wide reset deterministically leaks that ctrl VSI because ice_reset_all_vfs() only invalidated ctrl_vsi_idx instead of calling ice_vf_ctrl_vsi_release(); the commit reproduces this reliably and the attacker controls the FDIR setup side of the race.\nPR:N - No host root or CAP_SYS_ADMIN is required on the vulnerable host: a tenant with an assigned SR-IOV VF can negotiate VIRTCHNL_VF_OFFLOAD_FDIR_PF and send VIRTCHNL_OP_ADD_FDIR_FILTER over the VF mailbox to create the ctrl VSI; PF-wide resets occur during normal firmware/PCI/driver recovery without further host credentials.\nUI:N - Exploitation does not require any victim user action such as opening files or clicking links; a malicious VM tenant programs FDIR filters via the standard iAVF virtchnl interface and the leak triggers automatically on subsequent PF-wide reset events.\nS:C - The vulnerable ice driver runs in the host kernel but is triggered from an SR-IOV VF guest security domain; leaked ctrl VSIs consume finite pf->vsi slots and hardware VSI resources on the host, degrading or denying NIC functionality for the hypervisor and other VMs on the same PF.\nC:N - This is a kernel resource leak (orphaned ICE_VSI_CTRL structures and associated queue/MSI-X/FDIR hardware resources) without out-of-bounds read, use-after-free, or other memory disclosure primitive; no confidential data is exposed.\nI:N - The flaw only fails to call ice_vsi_release()/ice_vsi_delete_from_hw() for per-VF ctrl VSIs during ice_reset_all_vfs(); it does not corrupt memory, modify data, or provide write or code-execution primitives.\nA:H - Each leaked ctrl VSI permanently consumes a limited VSI slot (pf->num_alloc_vsi) and hardware resources; repeated PF-wide resets with FDIR-enabled VFs can exhaust the VSI pool causing ice_vsi_alloc() failure and denial of network service for the host and all co-resident VFs on the NIC."
