CVE-2026-53190

CVE-2026-53190 concerns a Linux kernel vulnerability in the drm/virtio path where a refcount leak could occur in error handling of virtio_gpu_dma_fence_wait(). The root cause is that dma_fence_unwrap_for_each() calls dma_fence_unwrap_first(), which assigns cursor->chain = dma_fence_get(head) (...

CVE-2026-53132

CVE-2026-53132 affects the Linux kernel vsock/virtio, where receiving zero-length packets with VIRTIO_VSOCK_SEQ_EOM could cause an unbounded skb queue growth, exhausting memory. The root cause is a miscalculation of backlog: vvs->rx_bytes + len > vvs->buf_alloc allows large queues when l...
