CVE-2026-68356

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A division by zero occurs in the airoha watchdog driver when the clock frequency is zero. This happens because the clk get rate() function can return 0 if the clock provider is unmanaged or improperly configured. The driver then uses the wdt freq variable as a divisor within the airoha wdt probe() function to calculate max timeout and within the airoha wdt get timeleft() function to calculate the remaining time.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
