CVE-2026-46155

In the Linux kernel, the following vulnerability has been resolved:

smb/client: fix out-of-bounds read in smb2_compound_op()

If a server sends a truncated response but a large OutputBufferLength, and

terminates the EA list early, check_wsl_eas() returns success without

validating that the entire OutputBufferLength fits within iov_len.

Then smb2_compound_op() does:

memcpy(idata->wsl.eas, data[0], size[0]);

Where size[0] is OutputBufferLength. If iov_len is smaller than size[0],

memcpy can read beyond the end of the rsp_iov allocation and leak adjacent

kernel heap memory.
