EUVD-2026-71289

In the Linux kernel, the following vulnerability has been resolved: batman-adv: reject unrepresentable multicast TVLV offsets The network and transport header fields in struct skbuff are 16-bit offsets from skb-head, and U16MAX is reserved as the unset transport header value. batadvtvlvcallhandle...

CVE-2026-80839

CVE-2026-80839 affects the batman-adv module in the Linux kernel . The root cause is that batadv_tvlv_call_handler() sets the 16-bit network and transport header offsets from a received multicast TVLV without validating whether the TVLV end offset is representable. When it exceeds the field's ran...

The vulnerability of the batadv_gw_node_delete() function in the net/batman-adv/gateway_client.c module, which is part of the Linux kernel’s networking functions, allows a hacker to cause a service failure.

The vulnerability of the batadvgwnodedelete function in the net/batman-adv/gatewayclient.c module, which is part of the Linux kernel’s networking functions, is related to state management errors. Exploiting this vulnerability could allow an attacker to cause service failures...

Linux Distros Unpatched Vulnerability : CVE-2026-80839

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - batman-adv: reject unrepresentable multicast TVLV offsets The network and transport header fields in struct skbuff are 16-bit offsets from skb-head, and U16MAX ...

The vulnerability of the batadv_dat_forward_data() function in the net/batman-adv/distributed-arp-table.c module, which is part of the networking functions of the Linux kernel, allows a hacker to trigger a service failure.

The vulnerability of the batadvdatforwarddata function in the net/batman-adv/distributed-arp-table.c module, which is part of the networking functions of the Linux kernel, stems from the lack of checking the return value. Exploiting this vulnerability could allow a remote attacker to cause a...

CVE-2026-80601

A flaw was found in the batman-adv Better Approach To Mobile Ad-hoc Networking - Advanced module of the Linux kernel. When the pskbmaypull function is called by batadvgetvid, it can reallocate the buffer, causing variables to point to a freed memory region. This use-after-free vulnerability could...

CVE-2026-80600

A flaw was found in the batman-adv module of the Linux kernel. This vulnerability occurs because the pskbmaypull function, when called by batadvgetvid, can reallocate a buffer. This causes variables to point to the previously freed memory, leading to a use-after-free condition. A local attacker...

CVE-2026-80599

A flaw was found in the Linux kernel's batman-adv Better Approach To Mobile Ad-hoc Networking - Advanced module. An attacker, by sending specially crafted network packets, could trigger an out-of-bounds memory access in the batadvgetvid function. This occurs because the function fails to verify t...
