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 ...

CVE-2026-64212

In the Linux kernel, the WiFi driver iwlwifi/mld contains a use-after-free-like issue in iwl_mld_remove_link: link->fw_id was saved at the start but the pointer could be NULL when storing it, and the pointer is not checked after the link is freed. The fix frees the link at the end of the funct...

CVE-2026-64175

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mld: stop TX during firmware restart When iwlwifi firmware crashes e.g., NMIINTERRUPTUNKNOWN on Intel BE201/Wi-Fi 7, iwlmldnicerror sets mld-fwstatus.inhwrestart to true. However, iwlmldtxfromtxq does not check thi...

CVE-2026-64175

CVE-2026-64175 concerns the Linux kernel’s iwlwifi/iwl_mld stack. When the Intel BE201 Wi‑Fi 7 firmware restarts after a crash, the TX path lacked a guard like the RX path, so iwl_mld_tx_from_txq() could dequeue and push frames to the transport layer while the firmware was dead. This caused iwl_t...

CVE-2026-64037

Concrete details found: CVE-2026-64037 affects the Linux kernel’s wifi: iwlwifi: mld path. When AMSDU is disabled, max_tid_amsdu_len can be 1 (sentinel) and the code checks for zero but not for this sentinel, causing num_subframes to compute to 0 and gso_size to be 0. This triggers skb_gso_segmen...
