CVE-2026-46231 Details
Description
In the Linux kernel, the following vulnerability has been resolved: batman-adv: bla: put backbone reference on failed claim hash insert When batadv_bla_add_claim() fails to insert a new claim into the hash, it leaked a reference to the backbone_gw for which the claim was intended. Call batadv_backbone_gw_put() on the error path to release the reference and avoid leaking the backbone_gw object.
A vulnerability in the Linux kernel's batman-adv module has been addressed. The issue involved a memory leak of backbone gateway references when the function batadv_bla_add_claim() failed to insert a claim into the hash. The error handling path was missing a call to release the leaked reference, which could lead to unnecessary memory consumption.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability.
