Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is caused by an out of bounds access in
fill meta index() due to an inode having an invalid inode number of zero, which was not checked. This occurs when fill meta index() is called to allocate and fill a metadata index, but it suffers a data read error, aborts, and invalidates the newly returned empty metadata index by setting its inode number to zero. When fill meta index() is called again, locate meta index() returns the previous index because it matches the inode number of 0, leading to an out of bounds access. A patch has been added to check that the inode number is not zero when the inode is created, returning -EINVAL if it is.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
