CVE-2024-25744

En el kernel de Linux anterior a 6.6.7, un VMM que no es de confianza puede activar el manejo de llamadas al sistema int80 en cualquier punto dado. Esto está relacionado con arch/x86/coco/tdx/tdx.c y arch/x86/mm/mem_encrypt_amd.c.

A flaw was found in the Linux kernel. A VMM can inject external interrupts on any arbitrary vector at any time, which may allow the guest OS to be manipulated from the VMM side.

It was discovered that the CIFS network file system implementation in the Linux kernel did not properly validate certain SMB messages, leading to an out-of-bounds read vulnerability. An attacker could use this to cause a denial of service or possibly expose sensitive information. Supraja Sridhara, Benedict Schlüter, Mark Kuhne, Andrin Bertschi, and Shweta Shinde discovered that the Confidential Computing framework in the Linux kernel for x86 platforms did not properly handle 32-bit emulation on TDX and SEV. An attacker with access to the VMM could use this to cause a denial of service or possibly execute arbitrary code.
