In the Linux kernel, the following vulnerability has been resolved: usb: gadget: function: rndis: add length check to response query Add variable… (CVE-2026-68088)
A vulnerability in the Linux kernel's USB gadget function for RNDIS was resolved by adding length checks to response queries. The fix involves adding variable representations for BufLength and BufOffset in rndis_query_response() and performing length validation similar to rndis_set_response(). This prevents potential issues related to improper length handling in these response queries.
AI Analysis
Technical Summary
The Linux kernel vulnerability CVE-2026-68088 concerns the USB gadget function rndis, where the response query lacked proper length checks on BufLength and BufOffset parameters. The patch added variable representations for these parameters in rndis_query_response() and implemented length validation consistent with the handling in rndis_set_response(). This correction addresses potential risks from malformed or unexpected input lengths in the RNDIS response processing.
Potential Impact
The vulnerability could allow improper processing of USB RNDIS response queries due to missing length checks, which might lead to unexpected behavior or memory issues. However, specific impacts such as privilege escalation or denial of service are not detailed in the provided information.
Mitigation Recommendations
A fix has been applied to the Linux kernel to add length checks in the rndis_query_response() function. Users should update to the patched kernel version once available. Patch status is not explicitly confirmed in the input; therefore, check the official Linux kernel advisories or vendor sources for the exact patched versions and remediation guidance.
