Description OSIDB Bzimport 2026-08-15 06:22:04 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ice: fix FDIR CTRL VSI resource leak in ice_reset_all_vfs()

Resetting all VFs causes resource leak on VFs with FDIR filters
enabled as CTRL VSIs are only invalidated and not freed. Fix by using
ice_vf_ctrl_vsi_release() instead of ice_vf_ctrl_invalidate_vsi() which
aligns behavior with the ice_reset_vf() function.

Reproduction:
  echo 1 > /sys/class/net/$pf/device/sriov_numvfs
  ethtool -N $vf flow-type ether proto 0x9000 action 0
  echo 1 > /sys/class/net/$pf/device/reset
