CVE-2024-26684

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.

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.

Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service. It was discovered that the Open vSwitch implementation in the Linux kernel could overflow its stack during recursive action operations under certain conditions. A local attacker could use this to cause a denial of service.
