CVE-2024-58008

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-58008
In the Linux kernel, the following vulnerability has been resolved: KEYS: trusted: dcp: fix improper sg use with CONFIG_VMAP_STACK=y With vmalloc stack addresses enabled (CONFIG_VMAP_STACK=y) DCP trusted keys can crash during en- and decryption of the blob encryption key via the DCP crypto driver. This is caused by improperly using sg_init_one() with vmalloc'd stack buffers (plain_key_blob). Fix this by always using kmalloc() for buffers we give to the DCP crypto driver.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: KEYS: trusted: dcp: corrige el uso incorrecto de sg con CONFIG_VMAP_STACK=y Con las direcciones de pila vmalloc habilitadas (CONFIG_VMAP_STACK=y), las claves confiables de DCP pueden fallar durante el cifrado y descifrado de la clave de cifrado de blobs a través del controlador de cifrado DCP. Esto se debe al uso incorrecto de sg_init_one() con búferes de pila vmalloc (plain_key_blob). Solucione esto utilizando siempre kmalloc() para los búferes que le damos al controlador de cifrado DCP.
