Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.4.0-rc5
Description
The issue is related to the netfs module in the Linux kernel, where the function netfs rreq unlock folios() can cause an oops when a network filesystem using netfs implements a clamp length() function. This can lead to a denial of service. The problem arises when the function folio start fscache() is called multiple times for the same folio, resulting in a kernel bug. The estimated number of potentially affected devices is not specified.
Recommendations
To resolve the issue, update the Linux kernel to a version that includes the fix for the netfs vulnerability.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
