  3. CVE-2024-53241
In the Linux kernel, the following vulnerability has been resolved: x86/xen: don't do PV iret hypercall through hypercall page Instead of jumping to the Xen hypercall page for doing the iret hypercall, directly code the required sequence in xen-asm.S. This is done in preparation of no longer using hypercall page at all, as it has shown to cause problems with speculation mitigations. This is part of XSA-466 / CVE-2024-53241.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: x86/xen: no realizar la hiperllamada de PV iret a través de la página de hiperllamada En lugar de saltar a la página de hiperllamada de Xen para realizar la hiperllamada iret, codificar directamente la secuencia requerida en xen-asm.S. Esto se hace como preparación para no utilizar más la página de hiperllamada, ya que se ha demostrado que causa problemas con las mitigaciones de especulación. Esto es parte de XSA-466 / CVE-2024-53241.
