Google: sys-kernel/lakitu-kernel-6_1, sys-kernel/lakitu-kernel-6_6: security update to 18613.0.3

medium Tenable Cloud Security Plugin ID 471770

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, 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)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 18613.0.3 or later.
