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...

CVE-2026-46155

CVE-2026-46155 affects the Linux kernel SMB client. The vulnerability is an out-of-bounds read in smb2_compound_op() caused by memcpy reading size[0] (OutputBufferLength) when iov_len is smaller than that length after a truncated server response. This can leak adjacent kernel heap memory. Impact ...
