Description
This security bulletin contains information about 1 vulnerability.
1) Double free (CVE-ID: CVE-2024-3446)
CWE-ID: CWE-415 - Double Free
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a malicious guest to escalate privileges on the system.
The vulnerability exists due to a boundary error in QEMU virtio devices (virtio-gpu, virtio-serial-bus, virtio-crypto), where the mem_reentrancy_guard flag insufficiently protects against DMA reentrancy issues. A malicious guest can trigger a double free error and execute arbitrary code within the context of the QEMU process on the host.
