Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The vulnerability is related to the cachefiles function in the Linux kernel, where the reuse of
msg id after a maliciously completed reopen request can cause a read request to remain unprocessed and result in a hung task. This issue arises due to the incorrect allocation of msg id, which can be exploited to trigger a hung task when read requests are waiting for the reopen to complete. The cachefiles ondemand send req(OPEN) function is involved in this process, and the reuse of msg id can lead to unexpected behavior, including the execution of a successful copen when it is expected to fail.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
