TIMELINE Feb 19 Reserved by Linux May 1 Published (CNA: Linux) Aug 4 RESCORED — CVE-2024-27066 (Linux). CVSS 7.5 → 5.5 (NVD).
In the Linux kernel, the following vulnerability has been resolved: virtio: packed: fix unmap leak for indirect desc table When use_dma_api and premapped are true, then the do_unmap is false. Because the do_unmap is false, vring_unmap_extra_packed is not called by detach_buf_packed. if (unlikely(vq->do_unmap)) { curr = id; for (i = 0; i < state->num; i++) { vring_unmap_extra_packed(vq, &vq->packed.desc_extra[curr]); curr = vq->packed.desc_extra[curr].next; } } So the indirect desc table is not unmapped. This causes the unmap leak. So here, we check vq->use_dma_api instead. Synchronously, dma info is updated based on use_dma_api judgment This bug does not occur, because no driver use the premapped with indirect.
