Last modified
CVE-2026-68270 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: drm/sysfb: Avoid possible truncation with calculating visible size Calculating the visible size of the system framebuffer can result in truncation of the result. The calculation uses 32-bit arithmetics, which can overflow if the values for height and stride are large.
Description
In the Linux kernel, the following vulnerability has been resolved: drm/sysfb: Avoid possible truncation with calculating visible size Calculating the visible size of the system framebuffer can result in truncation of the result. The calculation uses 32-bit arithmetics, which can overflow if the values for height and stride are large. Fix the issue by multiplying with mul_u32_u32().
