Applicable for: Wind River Linux LTS 25
Component/s: Kernel
In the Linux kernel, the following vulnerability has been resolved:EOL][EOL]drm/sun4i: dsi: Prevent underflow when computing packet sizes[EOL][EOL]Currently, the packet overhead is subtracted using unsigned arithmetic.[EOL]With a short sync pulse, this could underflow and wrap around to near[EOL]the maximal u16 value. Fix this by using signed subtraction. The call to[EOL]max() will correctly handle any negative numbers that are produced.[EOL][EOL]Apply the same fix to the other timings, even though those subtractions[EOL]are less likely to underflow.
