CVE-2026-31440

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> dmaengine: idxd: Fix leaking event log memory<br /> <br /> During the device remove process, the device is reset, causing the<br /> configuration registers to go back to their default state, which is<br /> zero. As the driver is checking if the event log support was enabled<br /> before deallocating, it will fail if a reset happened before.<br /> <br /> Do not check if the support was enabled, the check for &amp;#39;idxd-&gt;evl&amp;#39;<br /> being valid (only allocated if the HW capability is available) is<br /> enough.
