What to do
AI-suggested
A fix has been applied to the Linux kernel to correct the boundary check and prevent out-of-bounds access. Users should update to the latest Linux kernel version containing this fix once it is available.
Description
A vulnerability in the Linux kernel's ASoC rsnd component could lead to a potential out-of-bounds access due to improper boundary checks on the component_dais array. This flaw was identified and fixed by ensuring correct handling of the array bounds.
