What the advisory describes
In the Linux kernel, the following vulnerability has been resolved: crypto: iaa - unmap dst before software fallback on decompress On a hardware analytics error, decompress retries through the software fallback, which writes req->dst with the CPU while it is still mapped DMA_FROM_DEVICE. With SWIOTLB active the later dma_unmap_sg() copies the stale bounce buffer over req->dst, corrupting the result. Unmap before the fallback runs. The async path unmaps inline; the sync path signals the retry with -EAGAIN so iaa_comp_adecompress() runs the fallback after unmapping.
Source: EUVD (ENISA), in the words of the advisory.
