In the Linux kernel, the following vulnerability has been resolved: drm/msm: Fix obj leak in VM_BIND error path If we fail a handle-lookup part way thru, we need to drop the already obtained obj references. Patchwork: https://patchwork.freedesktop.org/patch/669784/
AI Analysis
Technical Summary
CVE-2025-40069 addresses a resource leak in the Linux kernel's drm/msm driver. Specifically, if a handle lookup fails during the VM_BIND operation, the kernel did not release object references acquired before the failure, leading to an object reference leak. This vulnerability has been fixed by updating the error handling path to properly drop these references, preventing potential resource exhaustion or other impacts related to leaked kernel objects.
Potential Impact
The vulnerability could lead to a 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). Leaked kernel object references may cause resource exhaustion or instability in the kernel, potentially allowing an attacker with local privileges to compromise system stability or escalate privileges.
Mitigation Recommendations
A fix for this vulnerability is available as indicated by the resolved status in the Linux kernel. Users and administrators should apply the official Linux kernel updates that include the patch for CVE-2025-40069. Since this is not a cloud service, remediation depends on updating affected Linux kernel versions. Patch status is not explicitly confirmed in the input data; therefore, check the official Linux kernel advisories or the referenced patchwork link for the latest remediation guidance.
