DEBIAN-CVE-2026-64255

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mld: validate stamask before ffs in BA session handlers Three BA session handlers use ffsbadata-stamask - 1 to derive a station ID without checking that stamask is non-zero. When stamask is zero, ffs returns 0 and...

CVE-2026-64255

Summary: CVE-2026-64255 affects the Linux kernel WiFi stack (iwlwifi, MLD). Three BA session handlers compute station IDs with ffs(ba_data->sta_mask) - 1 without ensuring sta_mask is non-zero, causing an out-of-bounds access on fw_id_to_link_sta[] when sta_mask is zero (ffd returns 0, wrapped ...
