Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A use-after-free issue exists in the
batman-adv module. The batadv bla del backbone claims() function removes all claims for a backbone by dropping the link entry in the hash list. Because the list entry is one of the references that must be dropped via batadv claim put(), calling this function before the final access to the claim object can lead to the claim being freed by batadv claim release() before the list entry is actually dropped.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
