Description OSIDB Bzimport 2026-08-10 12:23:49 UTC
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().
