CVE-2026-68343 is an input-validation vulnerability in the Linux kernel SMB client's DFS referral processing. The parse_dfs_referrals() function validates the fixed referral entry array and, on the for-next branch, per-referral string offsets, but does not sufficiently validate PathConsumed before storing it. A malformed referral response with PathConsumed larger than the search-name length can cause subsequent DFS parsing to advance beyond the end of the path, potentially resulting in memory-safety problems.

A Linux kernel SMB client vulnerability caused by insufficient validation of the PathConsumed value in DFS referral responses. A malformed response can cause subsequent DFS parsing to advance beyond the end of the search path. The reference assigns a CVSS v3 base score of 9.1, indicating potential high confidentiality and availability impacts, although vendor severity is LOW. The listed Google COS kernel packages are fixed in version 19506.299.137 or later.
