Descriptions
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: idxd: fix wq cleanup of WQCFG registers
A pre-release silicon erratum workaround where wq reset does not clear
WQCFG registers was leaked into upstream code. Use wq reset command
instead of blasting the MMIO region. This also address an issue where
we clobber registers in future devices.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: dmaengine: idxd: corrige la limpieza de wq de los registros WQCFG. Se filtró en el código ascendente un workaround de errata de silicio de prelanzamiento en la que el restablecimiento de wq no borra los registros WQCFG. Utilice el comando wq reset en lugar de destruir la región MMIO. Esto también soluciona un problema por el cual golpeamos los registros en dispositivos futuros.
