AI-suggested
A patch is available and should be applied to affected Linux kernel versions to fix the resource leak in the ice driver. The fix replaces the resource invalidation call with a proper resource release function. Users should update to patched kernel versions as listed in the advisory. No additional mitigation is indicated by the vendor advisory.
Description
A resource leak vulnerability was fixed in the Linux kernel's ice network driver. The flaw occurred when resetting all virtual functions (VFs) with Flow Director (FDIR) filters enabled, where control VSI resources were invalidated but not freed, causing a resource leak. This was corrected by changing the resource release method to properly free the resources. The vulnerability affects specific Linux kernel versions and has a CVSS score of 7.1, indicating a medium severity with high impact on availability. A patch is available to address this issue.
