In the Linux kernel, the following vulnerability has been resolved:EOL][EOL]regulator: core: fix NULL dereference on unbind due to stale coupling data[EOL][EOL]Failing to reset coupling_desc.n_coupled after freeing coupled_rdevs can[EOL]lead to NULL pointer dereference when regulators are accessed post-unbind.[EOL][EOL]This can happen during runtime PM or other regulator operations that rely[EOL]on coupling metadata.[EOL][EOL]For example, on ridesx4, unbinding the 'reg-dummy' platform device triggers[EOL]a panic in regulator_lock_recursive() due to stale coupling state.[EOL][EOL]Ensure n_coupled is set to 0 to prevent access to invalid pointers.
