CVE-2025-38032 is a medium severity vulnerability in the Linux kernel related to the ipmr_can_free_table() checks in the multicast routing (mr) code. The flaw involves a kernel warning and potential crash (splat) during the ipmr net namespace cleanup path when CONFIG_IP_MROUTE_MULTIPLE_TABLES is disabled. The issue stems from a loose sanity check that was consolidated into a single helper function to improve robustness. This vulnerability affects kernel stability but does not impact confidentiality or integrity.
