CVE-2024-8612
MediumSummary
W QEMU znaleziono lukę w urządzeniach virtio-scsi, virtio-blk i virtio-crypto. Rozmiar ustawiony dla funkcji virtqueue_push w virtio_scsi_complete_req, virtio_blk_req_complete oraz virtio_crypto_req_complete może być większy niż rzeczywisty rozmiar danych wysłanych do gościa.
Risk Assessment
Luka ta może prowadzić do nieprawidłowego przetwarzania danych, co stwarza ryzyko wycieku informacji lub awarii systemu. Organizacje korzystające z tych urządzeń mogą być narażone na ataki wykorzystujące tę podatność.
Recommendation
Zaleca się aktualizację QEMU do najnowszej wersji, w której ta luka została załatana. Należy również monitorować systemy pod kątem nieautoryzowanego dostępu.
