Descriptions
In the Linux kernel, the following vulnerability has been resolved:
dmaengine: idxd: Fix possible Use-After-Free in irq_process_work_list
Use list_for_each_entry_safe() to allow iterating through the list and
deleting the entry in the iteration process. The descriptor is freed via
idxd_desc_complete() and there's a slight chance may cause issue for
the list iterator when the descriptor is reused by another thread
without it being deleted from the list.
A vulnerability was found in the Linux kernel's DMA engine component in the irq_process_work_list() function. A possible use-after-free condition can occur during list iteration, which is because a descriptor may be freed while another thread is reusing it, potentially leading to access to freed memory.
