CVE ID :CVE-2026-64255<\/p>\n

Description :In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
wifi: iwlwifi: mld: validate sta_mask before ffs() in BA session handlers<\/p>\n
Three BA session handlers use ffs(ba_data->sta_mask) – 1 to derive a
\nstation ID without checking that sta_mask is non-zero. When sta_mask is
\nzero, ffs() returns 0 and the subtraction wraps to 0xFFFFFFFF, causing
\nan out-of-bounds access on fw_id_to_link_sta[].<\/p>\n
Add WARN_ON_ONCE(!ba_data->sta_mask) guards before each ffs() call,
\nconsistent with the existing check in iwl_mld_ampdu_rx_start().<\/p>\n
Severity: 0.0 | NA<\/p>\n
