  "description": "In the Linux kernel, the following vulnerability has been resolved:  hwmon: (occ) Fix division by zero in occ_show_power_1()  In occ_show_power_1() case 1, the accumulator is divided by update_tag without checking for zero. If no samples have been collected yet (e.g. during early boot when the sensor block is included but hasn\u0027t been updated), update_tag is zero, causing a kernel divide-by-zero crash.  The 2019 fix in commit 211186cae14d (\u0022hwmon: (occ) Fix division by zero issue\u0022) only addressed occ_get_powr_avg() used by occ_show_power_2() and occ_show_power_a0(). This separate code path in occ_show_power_1() was missed.  Fix this by reusing the existing occ_get_powr_avg() helper, which already handles the zero-sample case and uses mul_u64_u32_div() to multiply before dividing for better precision. Move the helper above occ_show_power_1() so it is visible at the call site.  [groeck: Fix alignment problems reported by checkpatch]",
