CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's ice driver, specifically related to the handling of Virtual Functions (VFs) with Flow Director (FDIR) filters during a reset operation. This flaw can lead to resource leaks, as the control Virtual Station Interfaces (VSIs) are not properly freed, potentially resulting in degraded performance or instability in network operations. Organizations utilizing the Linux kernel with SR-IOV (Single Root I/O Virtualization) should prioritize addressing this issue to ensure optimal resource management and system reliability.
Original NVD 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
