What it is

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

ASoC: rsnd: Fix potential out-of-bounds access of component_dais[]

component_dais[RSND_MAX_COMPONENT] is initially zero-initialized

and later populated in rsnd_dai_of_node(). However, the existing boundary check:

if (i >= RSND_MAX_COMPONENT)

does not guarantee that the last valid element remains zero. As a result,

the loop can rely on component_dais[RSND_MAX_COMPONENT] being zero,

which may lead to an out-of-bounds access.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
