An issue was discovered in the Linux kernel before 5.19. In pxa3xx_gcu_write in drivers/video/fbdev/pxa3xx-gcu.c the count parameter has a type conflict of size_t versus int causing an integer overflow and bypassing the size check. After that because it is used as the third argument to copy_from_user() a heap overflow may occur. NOTE: the original discoverer disputes that the overflow can actually happen.
