Description OSIDB Bzimport 2026-05-06 13:03:11 UTC
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.
