Description
A vulnerability in the Linux kernel's wifi cfg80211 subsystem could cause inconsistent network namespace states if renaming the wiphy device fails during a namespace switch. This issue occurs due to allocation failures during the rename operation, potentially leaving the device split across two namespaces and triggering kernel warnings.
