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...

EUVD-2026-45860

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-2026-64037 wifi: iwlwifi: mld: fix TSO segmentation explosion when AMSDU is disabled

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mld: fix TSO segmentation explosion when AMSDU is disabled When the TLC notification disables AMSDU for a TID, the MLD driver sets maxtidamsdulen to the sentinel value 1. The TSO segmentation path in...

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...
