CVE-2026-68270

Estado: RecibidaSin puntuar—

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().
