Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw within the
nfs4 setup readdir() function related to insufficient locking when dereferencing ->d parent->d inode. This condition could potentially lead to a race condition, although exploiting it on physical hardware is considered difficult. The issue stems from the use of xdr encode hyper(), which calls put unaligned be64().Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
