CVE-2025-38270

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: drv: netdevsim: don&amp;#39;t napi_complete() from netpoll<br /> <br /> netdevsim supports netpoll. Make sure we don&amp;#39;t call napi_complete()<br /> from it, since it may not be scheduled. Breno reports hitting a<br /> warning in napi_complete_done():<br /> <br /> WARNING: CPU: 14 PID: 104 at net/core/dev.c:6592 napi_complete_done+0x2cc/0x560<br /> __napi_poll+0x2d8/0x3a0<br /> handle_softirqs+0x1fe/0x710<br /> <br /> This is presumably after netpoll stole the SCHED bit prematurely.
