Proceed to\nath12k_dp_rx_peer_tid_delete() starting from unallocated tid,\nwhich might leads to freeing unallocated TID and cause potential\ncrash or out-of-bounds access.\n\nHence, fix by correctly decrementing tid before cleanup to match only\nthe successfully allocated TIDs.\n\nAlso, remove tid-- from failure case of ath12k_dp_rx_peer_frag_setup(),\nas decrementing the tid before cleanup in loop will take care of this.\n\nCompile tested only.","state":0,"publishedAt":"2025-09-11T16:52:21.917+00:00","modifiedAt":"2026-10-15T22:02:31.513+00:00","affected":[{"ecosystem":"Vendor
