> DESCRIPTION

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.
