CVE-2026-80596Hinoki check available

Local crash via misexposed sysfs attributes

Published Aug 28, 2026 · Updated Aug 28, 2026

Kernel input-driver flaw in Linux 6.11 allows local users to crash the system by accessing ims-pcu sysfs attributes on a data interface. The ims-pcu driver-core device groups expose main and OFN attributes on a manually claimed secondary interface whose descriptors and internal state cannot service them. Access requires a local ims-pcu device with its secondary interface bound; invoking the misplaced attributes can crash the host.
