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

Description A memory leak exists in the ath12k qmi driver event work() function within the ath12k driver. The issue occurs when the ATH12K FLAG UNREGISTERING bit is set, preventing the proper freeing of a buffer pointed to by the event variable, leading to a memory leak. The fix involves adding a 'goto skip' statement to ensure the event and associated list entries are correctly freed.
