AI-suggested
A patch is available and should be applied to affected Linux kernel versions. The vendor advisory confirms that this issue has been fixed. Users should update their Linux kernel to a patched version to mitigate this vulnerability.
Description
A vulnerability in the Linux kernel's ims-pcu driver was resolved by verifying the control endpoint type. The driver previously assumed the first endpoint of the control interface was an interrupt IN endpoint without validation. A malicious USB device could exploit this by providing a different endpoint type, causing kernel warnings or undefined behavior. This issue has been patched.
