CVE-2026-80939

A flaw was found in the Linux kernel's rtw89 PCI driver. During a warm reboot on ARM64 platforms, the driver's missing shutdown callback fails to stop radio frequency kill rfkill polling. This leads to attempts to read from a non-responding device, causing a fatal asynchronous SError and resultin...

CVE-2026-80939

CVE-2026-80939 affects the Linux kernel rtw89 PCI WiFi driver on arm64 platforms. The root cause is a missing .shutdown callback: during warm reboot the kernel invokes device_shutdown() but not .remove(), so the rfkill polling workqueue continues issuing MMIO reads to the PCI device after the PCI...
