Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> Input: ims-pcu - fix potential infinite loop in CDC union descriptor parsing<br /> <br /> The driver parses CDC union descriptors in ims_pcu_get_cdc_union_desc()<br /> by iterating through the extra descriptor data. However, it does not<br /> verify that the bLength of each descriptor is at least 2. A malicious<br /> device could provide a descriptor with bLength = 0, leading to an<br /> infinite loop in the driver.<br /> <br /> Add a check to ensure bLength is at least 2 before proceeding with<br /> parsing.
