Linux Distros Unpatched Vulnerability : CVE-2026-93203
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: avoid CRC corruption due to parallel claim add batadvblaaddclaim is used to add claims and modify the backbone of claims for CLAIM frames from...
CVE-2026-93203 batman-adv: bla: avoid CRC corruption due to parallel claim add
In the Linux kernel, the following vulnerability has been resolved: batman-adv: bla: avoid CRC corruption due to parallel claim add batadvblaaddclaim is used to add claims and modify the backbone of claims for CLAIM frames from remote backbones and local packets. When it handles a claim, it needs...

CVE-2026-93203
CVE-2026-93203 is a race condition in the Linux kernel's batman-adv mesh networking module, specifically in the Bridge Loop Avoidance (BLA) subsystem. The function batadv_bla_add_claim() can corrupt the CRC16 of backbone gateway entries when a new claim and a backbone ownership change execute in ...
DEBIAN-CVE-2026-89948
In the Linux kernel, the following vulnerability has been resolved: batman-adv: bla: fix freeing of claims on meshif deletion When the mesh interface is getting deleted, then batadvbladelbackboneclaims via batadvblapurgebackbonegw could make sure that all claims gets removed. But this function is...
CVE-2026-89948
CVE-2026-89948 affects the batman-adv (B.A.T.M.A.N. advanced) module in the Linux kernel , specifically its BLA (Backbone Link Aggregation) subsystem. The root cause is a logic bug: when a mesh interface is deleted, batadv_bla_del_backbone_claims() is never actually executed because bat_priv->...

Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: batman-adv: Hold the reference to the backbone gateways. The batadvblaaddclaim function can replace claim-backbonegw, and drop the last reference of the old gateway while the readers still follow the pointer. The netlink claim du...
CVE-2026-72233
In the Linux kernel, the following vulnerability has been resolved: batman-adv: bla: reacquire gw address after skb realloc The pskbmaypull called by batadvblaisbackbonegw could reallocate the buffer behind the skb. Variables which were pointing to the old buffer need to be reassigned to avoid an...

CVE-2026-64095
In the Linux kernel, the following vulnerability has been resolved: batman-adv: bla: avoid double decrement of bla.numrequests The bla.numrequests is increased when no requestsent was in progress. And it is decremented in various places announcement was received, backbone is purged, periodic work...
CVE-2026-64095
Concrete details confirm CVE-2026-64095 affects Linux kernel batman-adv (bla.num_requests) where double decrement occurs due to non-atomic checks of request_sent and bla.num_requests. The root cause: several code paths modify state and counts without atomic synchronization, allowing TOCTOU races....
