CVE-2026-31436 Details
Description
In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: fix possible wrong descriptor completion in llist_abort_desc() At the end of this function, d is the traversal cursor of flist, but the code completes found instead. This can lead to issues such as NULL pointer dereferences, double completion, or descriptor leaks. Fix this by completing d instead of found in the final list_for_each_entry_safe() loop.
A vulnerability has been identified in the Linux kernel's DMA engine component, specifically within the Intel Integrated Accelerator (IAA) crypto support. The issue arises in the 'llist_abort_desc()' function, where the wrong descriptor completion can lead to potential NULL pointer dereferences, double completions, or descriptor leaks. This vulnerability affects the stable versions of the Linux kernel.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability.
