medium Tenable Cloud Security Plugin ID 471479

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: netfilter: nf_conntrack_sip: fix use
of uninitialized rtp_addr in process_sdp process_sdp() declares union nf_inet_addr rtp_addr on the stack
and passes it to the nf_nat_sip sdp_session hook after walking the SDP media descriptions. However
rtp_addr is only initialized inside the media loop when a recognized media type with a non-zero port is
found. If the SDP body contains no m= lines, only inactive media sections (m=audio 0 ...) or only
unrecognized media types, rtp_addr is never assigned. Despite that, the function still calls
hooks->sdp_session() with &rtp_addr, causing nf_nat_sdp_session() to format the stale stack value as an IP
address and rewrite the SDP session owner and connection lines with it. With CONFIG_INIT_STACK_ALL_ZERO
(default on most distributions) this results in the session-level o= and c= addresses being rewritten to
0.0.0.0 for inactive SDP sessions. Without stack auto-init the rewritten address is whatever happened to
be on the stack. Fix this by pre-initializing rtp_addr from the session-level connection address (caddr)
when available, and tracking via a have_rtp_addr flag whether any valid address was established. Skip the
sdp_session hook entirely when no valid address exists. (CVE-2026-31427)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.534.95 or later.
