CVE-2026-46155 is an out-of-bounds read vulnerability in the Linux kernel SMB client function smb2_compound_op(). A server response can contain a truncated output buffer, an oversized OutputBufferLength, and an early-terminated extended attribute (EA) list. In this case, check_wsl_eas() returns success without verifying that the entire declared output buffer fits within iov_len. smb2_compound_op() subsequently uses OutputBufferLength as the memcpy() length, reading beyond the response allocation and potentially exposing adjacent kernel heap memory.
