Linux hwe edge: In the Linux kernel, the following vulnerability has been resolved: i40e: fix validation of VF state in get resources VF state I40E_VF_STATE_ACTIVE… (CVE-2025-39969)
In the Linux kernel, the following vulnerability has been resolved: i40e: fix validation of VF state in get resources VF state I40E_VF_STATE_ACTIVE is not the only state in which VF is actually active so it should not be used to determine if a VF is allowed to obtain resources. Use I40E_VF_STATE_RESOURCES_LOADED that is set only in i40e_vc_get_vf_resources_msg() and cleared during reset.
AI Analysis
Technical Summary
The Linux kernel i40e driver had a vulnerability (CVE-2025-39969) related to improper validation of the VF state during resource allocation. The driver incorrectly used the VF state I40E_VF_STATE_ACTIVE as the sole indicator of an active VF, which was insufficient because other states also represent active VFs. This flaw could allow a VF to obtain resources improperly. The fix involves switching to the I40E_VF_STATE_RESOURCES_LOADED state for validation, which is more accurate as it is set only during resource allocation and cleared on reset.
Potential Impact
The vulnerability could allow improper resource allocation to Virtual Functions in the i40e driver, potentially leading to confidentiality, integrity, and availability impacts as indicated by the CVSS vector (Confidentiality: High, Integrity: High, Availability: High). This means an attacker with local privileges could exploit this flaw to gain unauthorized access or disrupt system operations.
Mitigation Recommendations
A fix for this vulnerability has been implemented in the Linux kernel i40e driver by correcting the VF state validation logic. Users should apply the official Linux kernel updates that include this fix. Since no specific patch links or affected versions are provided, check the vendor or Linux kernel advisory for the exact fixed versions and apply updates accordingly.
