CVE-2026-52922

A flaw was found in the Linux kernel's batman-adv Better Approach To Mobile Ad-hoc Networking module. This vulnerability occurs because the batadvdatforwarddata function fails to validate the success of a memory allocation operation. An attacker could exploit this by triggering a scenario where t...

CVE-2026-52916

A flaw was found in the Linux kernel's batman-adv module. A remote attacker can exploit this vulnerability by sending specially crafted BATADVUNICASTFRAG packets, which are designed to contain other fragmented packets. This 'fragments in fragments' scenario causes the kernel to recursively proces...

Linux Distros Unpatched Vulnerability : CVE-2026-46231

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - batman-adv: bla: put backbone reference on failed claim hash insert When batadvblaaddclaim fails to insert a new claim into the hash, it leaked a reference to t...

CVE-2026-46233

A flaw was found in the Linux kernel's batman-adv module. This vulnerability allows a local attacker to trigger a NULL-pointer dereference within the batadvblapurgeclaims function. This issue arises from a timing conflict when a claim is being released simultaneously, causing a critical pointer t...

CVE-2026-43382

A flaw was found in the batman-adv module of the Linux kernel. This vulnerability occurs when the batadvvelpgetthroughput function attempts to acquire a network lock RTNL lock that is already held, particularly during the cancellation of a work queue item. This can lead to a deadlock, causing a...

CVE-2026-31683

A flaw was found in the batman-adv module of the Linux kernel. This vulnerability arises when the Optimized Global Messaging OGM aggregation state is dynamically altered, leading to insufficient buffer space skb tailroom for network packets. A remote attacker could exploit this condition by sendi...

PT-2025-38546

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The batadv nc skb decode packet function in the batman-adv module does not properly validate the coded len variable, potentially leading to out-of-bounds read and write issues during...
