In the Linux kernel, the following vulnerability has been resolved:
media: iris: Add buffer to list only after successful allocation
Move `list_add_tail()` to after `dma_alloc_attrs()` succeeds when creating
internal buffers. Previously, the buffer was enqueued in `buffers->list`
before the DMA allocation. If the allocation failed, the function returned
`-ENOMEM` while leaving a partially initialized buffer in the list, which
could lead to inconsistent state and potential leaks.
By adding the buffer to the list only after `dma_alloc_attrs()` succeeds,
we ensure the list contains only valid, fully initialized buffers.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
