CVE-2026-89631

A flaw was found in the Linux kernel's Server Message Block SMB client. A remote malicious SMB server could send a specially crafted tree connect response with a byte count that is too small. This incorrect handling can lead to an integer underflow, causing the client to read beyond an allocated...
