CVE-2024-26816

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-26816
In the Linux kernel, the following vulnerability has been resolved: x86, relocs: Ignore relocations in .notes section When building with CONFIG_XEN_PV=y, .text symbols are emitted into the .notes section so that Xen can find the "startup_xen" entry point. This information is used prior to booting the kernel, so relocations are not useful. In fact, performing relocations against the .notes section means that the KASLR base is exposed since /sys/kernel/notes is world-readable. To avoid leaking the KASLR base without breaking unprivileged tools that are expecting to read /sys/kernel/notes, skip performing relocations in the .notes section. The values readable in .notes are then identical to those found in System.map.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: x86, relocs: ignorar reubicaciones en la sección .notes Al compilar con CONFIG_XEN_PV=y, los símbolos .text se emiten en la sección .notes para que Xen pueda encontrar el punto de entrada "startup_xen" . Esta información se utiliza antes de iniciar el kernel, por lo que las reubicaciones no son útiles. De hecho, realizar reubicaciones en la sección .notes significa que la base KASLR está expuesta ya que /sys/kernel/notes es legible en todo el mundo. Para evitar filtrar la base de KASLR sin dañar las herramientas sin privilegios que esperan leer /sys/kernel/notes, omita realizar reubicaciones en la sección .notes. Los valores legibles en .notes son idénticos a los que se encuentran en System.map.
