CVE-2026-89633

A flaw was found in the Linux kernel's Server Message Block SMB client. The coalescet2 function processes server-supplied DataOffset fields without proper validation against buffer boundaries. A remote attacker could exploit this by crafting malicious SMB responses. This could lead to out-of-boun...

CVE-2026-89631

CVE-2026-89631 affects the Linux kernel SMB (CIFS) client . In CIFSTCon(), the strnlen() bound over the byte area uses the server's ByteCount minus two; when ByteCount is 0 or 1, the value underflows to a huge size_t, causing cifs_strndup_from_utf16() to read up to 65,535 bytes past the ~16 KB sl...
