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.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · affected: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat OpenShift Container Platform 4 · no fix planned: Red Hat Enterprise Linux 10, Red Hat Enterprise Linux 8, Red Hat Enterprise Linux 9, Red Hat OpenShift Container Platform 4 · updated 2026-10-24 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-98499.json)\n\n**kernel: HID: wacom: fix OOB read in wacom_wac_pen_serial_enforce()** — rated Moderate by Red Hat.
