CVE-2024-56564

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-56564
In the Linux kernel, the following vulnerability has been resolved: ceph: pass cred pointer to ceph_mds_auth_match() This eliminates a redundant get_current_cred() call, because ceph_mds_check_access() has already obtained this pointer. As a side effect, this also fixes a reference leak in ceph_mds_auth_match(): by omitting the get_current_cred() call, no additional cred reference is taken.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ceph: pasar el puntero de credenciales a ceph_mds_auth_match() Esto elimina una llamada get_current_cred() redundante, porque ceph_mds_check_access() ya ha obtenido este puntero. Como efecto secundario, esto también corrige una fuga de referencia en ceph_mds_auth_match(): al omitir la llamada get_current_cred(), no se toma ninguna referencia de credenciales adicional.
