CVE-2024-50215

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-50215
In the Linux kernel, the following vulnerability has been resolved: nvmet-auth: assign dh_key to NULL after kfree_sensitive ctrl->dh_key might be used across multiple calls to nvmet_setup_dhgroup() for the same controller. So it's better to nullify it after release on error path in order to avoid double free later in nvmet_destroy_auth(). Found by Linux Verification Center (linuxtesting.org) with Svace.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nvmet-auth: asignar dh_key a NULL después de que kfree_sensitive ctrl->dh_key se pudiera usar en varias llamadas a nvmet_setup_dhgroup() para el mismo controlador. Por lo tanto, es mejor anularlo después de la liberación en la ruta de error para evitar una doble liberación más adelante en nvmet_destroy_auth(). Encontrado por Linux Verification Center (linuxtesting.org) con Svace.
