Описание
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: idxd: Fix leaking event log memory
During the device remove process, the device is reset, causing the configuration registers to go back to their default state, which is zero. As the driver is checking if the event log support was enabled before deallocating, it will fail if a reset happened before.
Do not check if the support was enabled, the check for 'idxd->evl' being valid (only allocated if the HW capability is available) is enough.
