CVE-2026-80941

A flaw was found in the rtw88 Wi-Fi driver of the Linux kernel. This issue occurs because the rtwtxqpushskb function fails to free a socket buffer skb when an error occurs during transmission. This oversight can lead to a memory leak, potentially impacting system stability and performance over ti...

CVE-2026-80940

A flaw was found in the Linux kernel's rtw88 PCI driver. During the probe process, if the NAPI Networked Attached Peripheral Interface setup fails, allocated PCI resources are not properly released. This resource leak could potentially lead to a Denial of Service DoS due to resource exhaustion,...

In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: pci: fix resource leak on failed NAPI setup rtwpciprobe allocates PCI resources through rtwpcisetupresource before it sets up NAPI. If rtwpcinapiinit fails, the error path jumps straight to errpcideclaim and skips...

CVE-2026-80941

CVE-2026-80941 affects the Linux kernel wifi: rtw88 driver. The root cause is in rtw_txq_push_skb() : when the skb passed to rtw_hci_tx_write() fails, the error path does not free the skb before returning. This leads to a potential memory leak in rtw_txq_push() , where a dequeued skb is passed to...

CVE-2026-80940

CVE-2026-80940 is a resource leak in the Linux kernel's rtw88 PCI Wi-Fi driver. When rtw_pci_napi_init() fails during device probing, the error path jumps to err_pci_declaim without calling rtw_pci_destroy(), leaving PCI resources allocated by rtw_pci_setup_resource() leaked. The fix adds a dedic...
