Lower severity and a low EPSS score (0.26%). Track it; it rarely justifies an emergency change on its own.
Description
In the Linux kernel, the following vulnerability has been resolved: clk: samsung: Fix UBSAN panic in samsung_clk_init() With UBSAN_ARRAY_BOUNDS=y, I'm hitting the below panic due to dereferencing `ctx->clk_data.hws` before setting `ctx->clk_data.num = nr_clks`. Move that up to fix the crash.
