Description

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.
