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

Description An issue exists in the ath12k wifi driver where a stale link mapping is retained in ahvif->links map. This occurs when an arvif is initialized in non-AP STA mode but MLO connection preparation fails before the arvif is created, leaving arvif->is created as false. Because link deletion only executes when arvif->is created is true, the error path fails to remove the entry. Consequently, initializing a new arvif with the same link id triggers a warning in the ath12k mac op change vif links() function.

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