- Summary
- CVE-2025-38668 affecting package kernel for versions less than 6.6.104.2-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
regulator: core: fix NULL dereference on unbind due to stale coupling data
Failing to reset couplingdesc.ncoupled after freeing coupled_rdevs can lead to NULL pointer dereference when regulators are accessed post-unbind.
This can happen during runtime PM or other regulator operations that rely on coupling metadata.
For example, on ridesx4, unbinding the 'reg-dummy' platform device triggers a panic in regulatorlockrecursive() due to stale coupling state.
Ensure n_coupled is set to 0 to prevent access to invalid pointers.
