| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.16.10
Description
The issue is related to the RNDIS USB gadget in the Linux kernel, which lacks validation of the size of the RNDIS MSG SET command. This can allow attackers to obtain sensitive information from kernel memory. The vulnerability is associated with information disclosure and can be exploited to gain unauthorized access to protected information.
Recommendations
For Linux kernel versions prior to 5.16.10, update to version 5.16.10 or later to resolve the issue. As a temporary workaround, consider disabling the RNDIS USB gadget functionality until a patch is available. Restrict access to the
rndis set response function in rndis.c to minimize the risk of exploitation. Avoid using the RNDIS MSG SET command in the affected API endpoint until the issue is resolved.Exploit
