High [CVE-2026-68343] validate DFS referral PathConsumed
CVE-2026-68343Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: smb: client: validate DFS referral PathConsumed parse_dfs_referrals() validates that the response contains the fixed referral entry array and, on for-next, the per-referral string offsets. However, the response also contains a PathConsumed value that is later used for DFS path parsing. Validate PathConsumed against the search name length before storing it in the parsed referral. A remote attacker could send a specially crafted SMB response containing a malformed Distributed File System (DFS) referral. This could cause the PathConsumed value to exceed the search name length, leading to an out-of-bounds read during DFS path parsing. This vulnerability may result in information disclosure or a denial of service. Red Hat…
