Summary
In the Linux kernel, the following vulnerability has been resolved: Input: ims-pcu - fix type confusion in CDC union descriptor parsing The driver currently trusts the bMasterInterface0 from the CDC union descriptor without verifying that it matches the interface being probed. This could lead to the driver overwriting the private data of another interface. Validate that the control interface found in the descriptor is indeed the one we are probing.
