A flaw was found in the Linux kernel's HID Intel QuickSPI driver. A local attacker can exploit a heap buffer overflow by providing a specially crafted report through a hidraw SET_REPORT/SET_FEATURE ioctl. This allows the attacker to overflow a buffer with controlled length and content, potentially leading to memory corruption or denial of service.
