Subject: CVE-2026-72425: ice: fix FDIR CTRL VSI resource leak in ice_reset_all_vfs()
Date: Sat, 15 Aug 2026 15:08:24 +0900 [thread overview]
Message-ID: <2026081526-CVE-2026-72425-6d2c@gregkh> (raw)
From: Greg Kroah-Hartman <gregkh@kernel.org>
Description
===========
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
The Linux kernel CVE team has assigned CVE-2026-72425 to this issue.

Mitigation
==========
The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes. Individual
changes are never tested alone, but rather are part of a larger kernel
release. Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all. If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
