Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: vsock: socket huérfano después de la liberación del transporte Durante la liberación del socket, se llama a sock_orphan() sin tener en cuenta que establece sk->sk_wq en NULL. Más tarde, si se habilita SO_LINGER, esto conduce a un puntero nulo desreferenciado en virtio_transport_wait_close(). Deja huérfano el socket solo después de la liberación del transporte. Revierte parcialmente el commit 'Fixes:'.

Summary (en) In the Linux kernel, the following vulnerability has been resolved: vsock: Orphan socket after transport release During socket release, sock_orphan() is called without considering that it sets sk->sk_wq to NULL. Later, if SO_LINGER is enabled, this leads to a null pointer dereferenced in virtio_transport_wait_close(). Orphan the socket only after transport release. Partially reverts the 'Fixes:' commit.
