Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
An integer overflow exists in the SMB client within the
symlink data() function. The issue occurs when the ALIGN() macro is used to process ErrorDataLength. If ErrorDataLength is near UINT32 MAX, the ALIGN() operation can wrap to 0, causing a bounds check to pass incorrectly. This results in the loop advancing by zero bytes, which can lead to an infinite loop and an out-of-bounds read where the pointer p points to stale data.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
