In the Linux kernel, the following vulnerability has been resolved: drm/vmwgfx: Fix Use-after-free in validation Nodes stored in the validation… (CVE-2025-40111)
A use-after-free vulnerability in the Linux kernel's drm/vmwgfx component was resolved. The issue involved nodes in the validation duplicates hashtable originating from an arena allocator that is cleared at the end of vmw_execbuf_process. One node escaped proper clearing due to premature resource destruction, leading to a use-after-free condition. This vulnerability has been fixed in the Linux kernel.
AI Analysis
Technical Summary
CVE-2025-40111 describes a use-after-free vulnerability in the Linux kernel's drm/vmwgfx driver. The vulnerability arises because nodes stored in the validation duplicates hashtable come from an arena allocator cleared at the end of vmw_execbuf_process. Although all nodes are expected to be cleared in vmw_validation_drop_ht, one node escaped this process due to its resource being destroyed prematurely, causing a use-after-free condition. This flaw could lead to high impact on confidentiality, integrity, and availability as indicated by the CVSS vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). The vulnerability has been resolved in the Linux kernel.
Potential Impact
The vulnerability allows a use-after-free condition that can lead to complete compromise of confidentiality, integrity, and availability of the affected system. The CVSS 3.1 vector rates the impact as high across all three security properties. Exploitation requires local access with low privileges and no user interaction, but the attack complexity is low.
Mitigation Recommendations
A fix for this vulnerability has been implemented in the Linux kernel. Users and administrators should apply the official Linux kernel updates that address CVE-2025-40111 to remediate this issue. Patch status is not explicitly confirmed in the provided data; therefore, verify with the official Linux kernel advisories for the exact fixed versions and update accordingly.
