Linux Kernel up to 7.2-rc2 rndis rndis_query_response BufLength/BufOffset buffer overflow

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Summaryinfo

A vulnerability described as very critical has been identified in Linux Kernel up to 7.2-rc2. This vulnerability affects the function rndis_query_response of the component rndis. Such manipulation of the argument BufLength/BufOffset leads to buffer overflow. This vulnerability is traded as CVE-2026-68088. The attack may be launched remotely. There is no exploit available.

Detailsinfo

A vulnerability, which was classified as very critical, has been found in Linux Kernel up to 7.2-rc2. Affected by this issue is the function rndis_query_response of the component rndis. The manipulation of the argument BufLength/BufOffset with an unknown input leads to a buffer overflow vulnerability. Using CWE to declare the problem leads to CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. Impacted is confidentiality, integrity, and availability. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: function: rndis: add length check to response query Add variable representations for BufLength and BufOffset in rndis_query_response(), and perform a length check on them. This is identical to how rndis_set_response() handles these parameters.

The advisory is available at git.kernel.org. This vulnerability is handled as CVE-2026-68088 since 07/30/2026. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $5k-$25k at the moment (estimation calculated on 08/10/2026).

Upgrading to version 5.10.261, 5.15.212, 6.1.178, 6.6.145, 6.12.96, 6.18.39, 7.1.4 or 7.2-rc3 eliminates this vulnerability. Applying the patch efcf4e4eeea0d69d8da72a7bc5cbd49b6192260e/bb2b4402b4571b0c989b977779f7be01107ca425/585921866d2d7d65d4b0d89927c78f784668cf5f/caea8b120604312bab2bfeb1a972f9cd17019e93/f5870777458d8be65d7cd08bc750a03f17998350/e01e7814b4223560eab0513b7c15b8c82bdc83f3/b09716040f3fa4a252eeda3ceb5295ea0e39c1fb/95f90eea070837f7c72207d5520f805bdefc3bc5 is able to eliminate this problem.
