CVE-2024-42291: ice: Add a per-VF limit on number of FDIR filters
First published: Sat Aug 17 2024(Updated: )
In the Linux kernel, the following vulnerability has been resolved: ice: Add a per-VF limit on number of FDIR filters While the iavf driver adds a s/w limit (128) on the number of FDIR filters that the VF can request, a malicious VF driver can request more than that and exhaust the resources for other VFs. Add a similar limit in ice.
