Answer in brief
CVE-2026-72394 records a Unknown severity vulnerability in hwmon: (aspeed-g6-pwm-tach) Guard fan RPM calculation against divide-by-zero. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In the Linux kernel, the following vulnerability has been resolved: hwmon: (aspeed-g6-pwm-tach) Guard fan RPM calculation against divide-by-zero Sashiko reports: In the aspeed-g6-pwm-tacho driver, the aspeed_tach_val_to_rpm() function calculates the fan RPM using the tachometer value. However, it does not check if the tachometer value is zero before performing the division. If the hardware reports a tachometer value of 0 (which can happen due to an extremely fast pulse, a stuck edge, or a hardware glitch), the calculated tach_div evaluates to 0. The subsequent call to do_div() with tach_div as the divisor triggers a divide-by-zero exception, leading to a kernel panic. Check the divisor against zero to fix the problem.
