A issue was discovered in the Linux kernel before version 5.19. In the pxa3xxgcuwrite function in drivers/video/fbdev/pxa3xx-gcu.c, the count parameter has a type conflict between sizet and int, which causes an integer overflow and bypasses the size check. Additionally, since this parameter is us...
