As a result, the corresponding MSDU is no longer referenced\nby the defragmentation path and is never freed.\n\nThis leads to a memory leak for the affected MSDU on this error path.\nProper cleanup is required to ensure the MSDU is released when header\nvalidation fails during TKIP MIC verification.\n\nTested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.1.c5-00302-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.115823.3\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
