NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-modules-wireless package and not the kernel-uek-modules-wireless package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

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.
