In the Linux kernel, the following vulnerability has been resolved: ethtool: tsconfig: fix missing ethnl_ops_complete() tsconfig_prepare_data()… (CVE-2026-64526)
A vulnerability in the Linux kernel's ethtool component related to the tsconfig functionality has been resolved. The issue involved a missing call to ethnl_ops_complete() after ethnl_ops_begin() was called in tsconfig_prepare_data(), which could lead to improper operation completion handling. This flaw has been fixed in the Linux kernel. No specific affected versions or exploitation details are provided.
AI Analysis
Technical Summary
The vulnerability in the Linux kernel concerns the ethtool tsconfig feature where tsconfig_prepare_data() calls ethnl_ops_begin() but fails to call ethnl_ops_complete() before returning an error. This missing call could cause incomplete operation handling within the kernel's ethtool interface. The issue has been addressed by ensuring ethnl_ops_complete() is called appropriately, resolving the vulnerability identified as CVE-2026-64526.
Potential Impact
The impact details are not explicitly described in the available data. The vulnerability relates to incomplete operation handling in the kernel's ethtool interface, which could potentially lead to inconsistent kernel state or resource management issues. There is no evidence of known exploits in the wild.
Mitigation Recommendations
A fix for this vulnerability has been implemented in the Linux kernel. Since no specific patch links or affected versions are provided, users should apply the latest Linux kernel updates from their distribution or vendor to ensure this issue is resolved. Patch status is not yet confirmed in detail—check the vendor advisory or Linux kernel release notes for current remediation guidance.
