Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
An out-of-bounds read exists in the
smb2 compound op() function. This occurs when a server sends a truncated response with a large OutputBufferLength and terminates the EA list early. In this scenario, the check wsl eas() function returns success without validating that the entire OutputBufferLength fits within iov len. Consequently, the memcpy() function may read beyond the end of the rsp iov allocation, potentially leaking adjacent kernel heap memory.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
