There is no fixed version for Centos:10 kernel-modules-extra-matched.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-modules-extra-matched package and not the kernel-modules-extra-matched package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

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

x86/fred: Correct speculative safety in fred_extint()

array_index_nospec() is no use if the result gets spilled to the stack, as it makes the believed safe-under-speculation value subject to memory predictions.

For all practical purposes, this means array_index_nospec() must be used in the expression that accesses the array.

As the code currently stands, it's the wrong side of irqentry_enter(), and 'index' is put into %ebp across the function call.

Remove the index variable and reposition array_index_nospec(), so it's calculated immediately before the array access.
