What does CVE-2024-36323 affect?
CVE-2024-36323 affects VCN-JPEG hardware cores, Virtualization environments using VCN-JPEG. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
What should I do about CVE-2024-36323?
Apply firmware/driver updates; verify VM isolation.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Allows a malicious guest VM or process to read/write the victim VM's JPEG core registers, risking data exposure and VM compromise.
