There exists a use-after-free vulnerability in the Linux kernel through iouring and the IORINGOPSPLICE operation. If IORINGOPSPLICE is missing the IOWQWORKFILES flag, which signals that the operation won't use current->nsproxy, so its reference counter is not increased. This assumption is not always true as calling iosplice on specific files will call the getuts function which will use current->nsproxy leading to invalidly decreasing its reference counter later causing the use-after-free vulnerability. We recommend upgrading to version 5.10.160 or above
