In the Linux kernel, the following vulnerability has been resolved: net: stmmac: xgmac: fix handling of DPP safety error for DMA channels Commit 56e58d6c8a56 ("net: stmmac: Implement Safety Features in XGMAC core") checks and reports safety errors, but leaves the Data Path Parity Errors for each channel in DMA unhandled at all, lead to a storm of interrupt. Fix it by checking and clearing the DMA_DPP_Interrupt_Status register. 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. • https://git.kernel.org/stable/c/56e58d6c8a5640eb708e85866e9d243d0357ee54 https://git.kernel.org/stable/c/e9837c83befb5b852fa76425dde98a87b737df00 https://git.kernel.org/stable/c/2fc45a4631ac7837a5c497cb4f7e2115d950fc37 https://git.kernel.org/stable/c/6609e98ed82966a1b3168c142aca30f8284a7b89 https://git.kernel.org/stable/c/e42ff0844fe418c7d03a14f9f90e1b91ba119591 https://git.kernel.org/stable/c/7e0ff50131e9d1aa507be8e670d38e9300a5f5bf https://git.kernel.org/stable/c/3b48c9e258c8691c2f093ee07b1ea3764caaa1b2 https://git.kernel.org/stable/c/46eba193d04f8bd717e525eb4110f3c46 •
