1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2024-25744)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to missing access restrictions related to arch/x86/coco/tdx/tdx.c and arch/x86/mm/mem_encrypt_amd.c. An untrusted VMM can trigger int80 syscall handling at any given point and perform a denial of service (DoS) attack.


2) Stack-based buffer overflow (CVE-ID: CVE-2023-52628)
