CVE-2026-43146 Details
Description
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.
A vulnerability exists in the Linux kernel's media iris component, where internal buffers were added to a list before confirming successful memory allocation. This issue, present in the stable Linux kernel, could result in a partially initialized buffer remaining in the list if the allocation failed, leading to potential memory leaks and an inconsistent state. The vulnerability has been addressed by modifying the buffer management to ensure that only fully initialized buffers are listed.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the patched version are available on the Linux kernel official website.
