Search: CVE-2025-39973

A vulnerability in the Linux kernel's i40e driver allowed the ring_len parameter from a virtual function to be assigned directly to hardware memory context without validation. This could lead to improper queue length settings. The issue has been fixed by adding upper boundary checks and enforcing alignment constraints on Tx and Rx queue lengths. The fix is included in security updates for SUSE Linux Enterprise and related distributions. Users must apply the update and reboot to ensure protection.
