Echo: linux: security update to 6.1.170-1

medium Tenable Self-Hosted Container Security Plugin ID 457098

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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't been updated), update_tag is zero, causing a kernel divide-by-zero crash. The 2019 fix in
commit 211186cae14d ("hwmon: (occ) Fix division by zero issue") 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
