In the Linux kernel, the following vulnerability has been resolved: ceph: fix inode reference leakage in ceph_get_snapdir() The ceph_get_inode() will search for or insert a new inode into the hash for the given vino, and return a reference to it. If new is non-NULL, its reference is consumed. We should release the reference when in error handing cases.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ceph: se corrige la fuga de referencia de inodo en ceph_get_snapdir(). ceph_get_inode() buscará o insertará un nuevo inodo en el hash para el vino dado y devolverá una referencia a él. Si new no es NULL, se consume su referencia. Deberíamos liberar la referencia en casos de manejo de errores.
