CVE-2026-46195

A flaw was found in the Linux kernel's Server Message Block (SMB) client. A malicious server can exploit this vulnerability on 32-bit systems by providing a crafted dacloffset value. This can cause a pointer wrap, leading to the dereferencing of invalid Discretionary Access Control List (DACL) fields during chmod or chown operations. This memory corruption could potentially allow the malicious server to bypass security mechanisms or cause a denial of service.
