A flaw was found in the Linux kernel, specifically within the intel-quickspi driver. This vulnerability allows a malicious Human Interface Device (HID) to send an oversized report, which is then copied into a buffer without proper size validation. This leads to a buffer overflow, a type of memory corruption, which could potentially allow an attacker to execute arbitrary code or cause a system crash (denial of service).
kernel: HID: intel-thc-hid: intel-quickspi: bound GET_REPORT response to the caller buffer — rated Moderate by Red Hat. Released 2026-09-11, updated 2026-09-18.
