CVE-2024-42291 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 0.23% chance of exploitation in the next 30 days.
