CVE-2026-80594

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw exists in the ims-pcu driver during the parsing of CDC union descriptors within the ims pcu get cdc union desc() function. The driver iterates through extra descriptor data without verifying that the bLength of each descriptor is at least 2. A malicious device could provide a descriptor where bLength is 0, causing the driver to enter an infinite loop.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
