CVE-2025-71143

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> clk: samsung: exynos-clkout: Assign .num before accessing .hws<br /> <br /> Commit f316cdff8d67 ("clk: Annotate struct clk_hw_onecell_data with<br /> __counted_by") annotated the hws member of &amp;#39;struct clk_hw_onecell_data&amp;#39;<br /> with __counted_by, which informs the bounds sanitizer (UBSAN_BOUNDS)<br /> about the number of elements in .hws[], so that it can warn when .hws[]<br /> is accessed out of bounds. As noted in that change, the __counted_by<br /> member must be initialized with the number of elements before the first<br /> array access happens, otherwise there will be a warning from each access<br /> prior to the initialization because the number of elements is zero. This<br /> occurs in exynos_clkout_probe() due to .num being assigned after .hws[]<br /> has been accessed:<br /> <br /> UBSAN: array-index-out-of-bounds in drivers/clk/samsung/clk-exynos-clkout.c:178:18<br /> index 0 is out of range for type &amp;#39;clk_hw *[*]&amp;#39;<br /> <br /> Move the .num initialization to before the first access of .hws[],<br /> clearing up the warning.
