high Tenable Self-Hosted Container Security Plugin ID 451787

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: net: do not leave a dangling sk
pointer, when socket creation fails It is possible to trigger a use-after-free by: * attaching an fentry
probe to __sock_release() and the probe calling the bpf_get_socket_cookie() helper * running traceroute -I
