Linux Distros Unpatched Vulnerability : CVE-2024-42246

medium Nessus Plugin ID 229031

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - In the Linux kernel, the following vulnerability has been resolved: 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
