CWE-ID: CWE-772 - Missing Release of Resource after Effective Lifetime

CVSSv4: 4.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to improper resource shutdown in netty_unix_socket_recvFd when receiving SCM_RIGHTS control messages containing two file descriptors over a unix domain socket. A remote attacker can send a specially crafted message to cause a denial of service.

The issue is reachable via Epoll/KQueue DomainSocketChannel only when the application enables DomainSocketReadMode.FILE_DESCRIPTORS.
