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