Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to a problem in the readahead code of the Linux kernel, which can cause the kernel to hang when used with NFS. The problem has been identified as being caused by a commit that attempted to properly shorten readahead when falling back to do page cache ra(). This can lead to reduced readahead throughput due to readahead window confusion. The cause of the problem is that ra->size can be shrunk by a read pages() call, resulting in a negative number of pages being passed to do page cache ra().

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
