Summary
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.
A flaw was found in the Linux kernel's RNDIS (Remote Network Driver Interface Specification) gadget function. A missing length check for `BufLength` and `BufOffset` parameters within the `rndis_query_response()` function could allow a malicious actor to provide specially crafted input.
This could lead to memory corruption, potentially resulting in a denial of service. Red Hat severity: not rated.
Weakness: CWE-805. Red Hat lists Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9 as not affected.
