Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.79%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
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.
