CVE-2021-46920

In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Fix clobbering of SWERR overflow bit on writeback Current code blindly writes over the SWERR and the OVERFLOW bits. Write back the bits actually read instead so the driver avoids clobbering the OVERFLOW bit that...

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...

kernel: dmaengine: qcom-adm: fix wrong calling convention for prep_slave_sg

A flaw was found in the Linux kernel’s dmaengine qcom-adm implementation where the function prepslavesg did not adhere to the documented error return convention. On error, it returned an error pointer instead of NULL, which can cause consumers that check only for non-NULL to assume success and...
