Deskripsi CVE
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.
