CVE-2021-46918

CVE-2021-46918 is a Linux kernel vulnerability in the IDXDMA/DMAR DMA engine where MSIX permission entries were not cleared on device shutdown. The issue arose because MSIX entries were left enabled and pasid entries remained programmed when the device shut down, potentially enabling persistence ...

CVE-2021-46919 dmaengine: idxd: fix wq size store permission state

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: fix wq size store permission state WQ size can only be changed when the device is disabled. Current code allows change when device is enabled but wq is disabled. Change the check to detect device state...

CVE-2021-46919

CVE-2021-46919 is a Linux kernel vulnerability in dmaengine/idxd where WQ size could be changed while the device was enabled. The fix changes the state check to ensure the WQ size is only modifiable when the device is disabled, addressing a race between device state and WQ configuration. Connecte...

CVE-2021-46917

CVE-2021-46917 is a Linux kernel vulnerability tied to the dmaengine: idxd subsystem. The issue stems from a pre-release silicon erratum workaround where a wq reset did not clear WQCFG registers, leaking into upstream code and risking clobbering registers on future devices. The documented fix rep...
