HighCVSS 7.8/10Last modified Oct 15, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

speakup: Fix sizeof() vs ARRAY_SIZE() bug

The "buf" pointer is an array of u16 values. This code should be using ARRAY_SIZE() (which is 256) instead of sizeof() (which is 512), otherwise it can the still got out of bounds.
