kernel: smb: client: fix OOB reads parsing symlink error response

A flaw was found in the Linux kernel's Server Message Block SMB client. A remote, untrusted server could send a specially crafted symlink error response, leading to an out-of-bounds read vulnerability. This could result in the disclosure of sensitive information from the kernel's memory to a loca...

CVE-2026-46185

The CVE-2026-46185 issue affects the Linux kernel SMB client. The root cause is insufficient length validation in smb2_check_message() when processing symlink error responses, allowing a symlink_data() path to read beyond the buffer if iov_len is smaller than the 64-byte SMB2 header and accessing...
