CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's framebuffer size calculation, where an integer overflow can occur during the multiplication of linebytes and height, potentially leading to undefined behavior. This issue could result in system instability or crashes if exploited. Organizations using Linux systems with graphical interfaces should prioritize this fix to mitigate the risk of operational disruptions.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: drm/sysfb: ofdrm: Fix integer overflow in fb_size calculation The framebuffer size calculation `fb_size = linebytes * height` can overflow when both values are large (e.g., 46341 * 46341 > INT_MAX). Since linebytes and height are both int types, the multiplication is performed as int * int, which results in undefined behavior on overflow. Use check_mul_overflow() to detect and prevent this overflow, consistent with the approach used in simpledrm.c and corebootdrm.c.
