Vulnerability from github – Published: 2026-05-06 12:30 – Updated: 2026-05-13 21:31

Details

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.

Severity ?

5.5 (Medium)

Vulnerability from cvelistv5 – Published: 2026-05-06 11:27 – Updated: 2026-05-11 22:18

Title

media: iris: Add buffer to list only after successful allocation

Summary

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.
