Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 在 Linux 内核中，已解决以下漏洞： net, sunrpc: Remap EPERM in case of connection failure in xs_tcp_setup_socket When using a BPF program on kernel_connect(), the call can return -EPERM. This causes xs_tcp_setup_socket() to loop forever, filling up the syslog and causing the kernel to potentially freeze up. Neil suggested: This will propagate -EPERM up into other layers which might not be ready to handle it. It might be safer to map EPERM to an error we would be more likely to expect from the network system - such as ECONNREFUSED or ENETDOWN. ECONNREFUSED as error seems reasonable.
    For programs setting a different error can be out of reach (see handling in 4fbac77d2d09) in particular on kernels which do not have f10d05966196 (bpf: Make BPF_PROG_RUN_ARRAY return -err instead of allow boolean), thus given that it is better to simply remap for consistent behavior. UDP does handle EPERM in xs_udp_send_request(). (CVE-2024-42246)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
