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.
A flaw was found in the Linux kernel's ims-pcu driver. A type confusion vulnerability exists in the CDC union descriptor parsing, where the driver trusts the bMasterInterface0 value without proper verification. This could allow a local attacker, or a malicious USB device, to overwrite the private data of another interface, potentially leading to a denial of service.
