Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to incorrect usage of
sb index in the md/md-bitmap component of the Linux kernel. This can cause a crash in a clustered environment due to wrong code logic for clustered-md, where the slot offset for cluster nodes is never set. The problem arises from the removal of page->index from bitmap code, which was done by commit d7038f951828. The call trace includes functions such as md bitmap file set bit, md bitmap startwrite, raid1 make request, and others, indicating the path of execution leading to the potential crash. The vulnerability may allow an attacker to cause a denial of service.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
