CVE-2026-80715

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> igc: remove napi_synchronize() in igc_down()<br /> <br /> When an AF_XDP zero-copy application is killed abruptly, the XSK pool is<br /> torn down but NAPI keeps polling. igc_clean_rx_irq_zc() then returns the<br /> full budget on every poll, so napi_complete_done() never clears<br /> NAPI_STATE_SCHED.<br /> <br /> igc_down() calls napi_synchronize() before napi_disable(), so it spins<br /> forever waiting for that bit and the interface never goes down. Drop the<br /> napi_synchronize() and let napi_disable() do the job -- it sets<br /> NAPI_STATE_DISABLE, which forces the stuck poll to complete. Reorder it<br /> ahead of igc_set_queue_napi() so the NAPI mapping is cleared only after<br /> polling has stopped, matching the recent igb fix b1e067240379.
