SUSE CVE-2026-63821

In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: usb: fix memory leaks on USB write failures When rtwusbwriteport fails to submit a USB Request Block URB e.g., due to device disconnect or ENOMEM, the completion callback is never executed. Currently, the driver...

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-2026-64155

The CVE-2026-64155 entry describes a Linux kernel fix in the ath11k WiFi driver (WMI WOW calls). Two error-path paths that returned the result of ath11k_wmi_cmd_send(...) without checking the return value could skip freeing the skb in error scenarios, potentially leaking resources. The patch adds...
