Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A race condition exists in the handling of NFS write requests within the Linux kernel. Specifically, the issue occurs when updating an existing write request after
nfs lock and join requests() checks if the request is still attached to the mapping. Without a lock on the page group, nfs inode remove request() can succeed prematurely, leading to potential races. The fix involves acquiring the page group lock earlier in nfs lock and join requests() and maintaining it during the removal of the request in nfs inode remove request().Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
