CVE-2024-26684

Estado: AnalizadaMedia (5.5)—
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: stmmac: xgmac: corrige el manejo del error de seguridad DPP para canales DMA. El commit 56e58d6c8a56 ("net: stmmac: Implement Safety Features in XGMAC core") verifica e informa errores de seguridad, pero deja sin controlar los errores de paridad de ruta de datos para cada canal en DMA, lo que provoca una tormenta de interrupciones. Solucionelo verificando y borrando el registro DMA_DPP_Interrupt_Status.
