CVE-2024-53055

Scan hang via overflowing 8-bit loop counter

Published Nov 19, 2024 · Updated May 11, 2026

Infinite loop in Linux iwlwifi MVM scan construction allows local users to hang 6 GHz scans with more than 255 colocated AP entries. In drivers/net/wireless/intel/iwlwifi/mvm/scan.c, an 8-bit iterator is compared with a 32-bit entry count, causing it to wrap before reaching counts above 255. The condition requires the iwlwifi MVM path, 6 GHz scanning, and over 255 colocated access points collected during earlier 2.4/5 GHz scans; the loop stalls scan processing.
