CVE-2024-36921

Out-of-bounds access via invalid station ID removal

Published May 30, 2024 · Updated Aug 5, 2026

Out-of-bounds array access in the Linux kernel 6.4 iwlwifi MVM driver allows adjacent attackers to corrupt kernel memory over Wi-Fi. The iwl_mvm_mld_rm_sta_id function uses a station identifier for array access without first rejecting IDs outside the valid station range. The affected path is reached during Intel wireless station removal when driver error handling leaves an invalid ID, exposing kernel confidentiality, integrity, and availability.
