A flaw was found in the Linux kernel's Wacom Human Interface Device (HID) driver. When processing a device report descriptor with mismatched usage and count configurations, the driver can calculate an invalid memory offset and perform an out-of-bounds read beyond the allocated report buffer. A local attacker could exploit this issue by connecting or emulating a specially crafted HID device, potentially allowing them to expose sensitive kernel memory to user space.
