Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
watchdog: airoha: Prevent division by zero when clock frequency is zero<br />
<br />
clk_get_rate() can return 0 when the clock provider is not properly<br />
configured or the clock is unmanaged. The driver uses wdt_freq as a<br />
divisor directly in airoha_wdt_probe() to compute max_timeout and in<br />
airoha_wdt_get_timeleft() to compute the remaining time, which results<br />
in a division by zero.<br />
<br />
Add a check for wdt_freq == 0 in probe and return -EINVAL with<br />
dev_err_probe() to prevent the division by zero and provide a<br />
diagnostic message.
