CVE-2026-72235

A flaw was found in the Linux kernel batman-adv component. The batadvinterfacerx function, responsible for handling network packets, can reallocate its internal buffer. However, a pointer to the ethernet header is not correctly updated after this reallocation. This oversight leads to a...

CVE-2026-72234

A flaw was found in the Linux kernel's batman-adv module. When the pskbmaypull function is called by batadvgetvid, it can reallocate a buffer. However, a pointer to the old buffer, specifically unicastpacket, was not correctly reassigned, leading to a use-after-free condition. This memory...

CVE-2026-72233

A flaw was found in the batman-adv component of the Linux kernel. This vulnerability occurs when a buffer is reallocated, but existing pointers are not updated, leading to a use-after-free condition. A local attacker could potentially exploit this to cause a system crash denial of service or, in...

CVE-2026-72232

A flaw was found in the batman-adv component of the Linux kernel. A local user with extended Berkeley Packet Filter eBPF traffic control TC hook access could exploit this by attaching a TC filter that truncates a packet and redirects it to a batman-adv interface. The batadvinterfacetx function th...

CVE-2026-72229

A flaw was found in the batman-adv component of the Linux kernel. When a mesh interface is registered, an untagged VLAN object is created. If the network device netdev registration fails due to a veto, the cleanup process does not properly free this object. This can lead to a memory leak,...

CVE-2026-72228

A flaw was found in the batman-adv component of the Linux kernel. This vulnerability occurs during the processing of network packets that have fragmented data. Specifically, if a packet's fragmented data fails a preparation step called linearization, a reference to a network interface primaryif i...

CVE-2026-72227

A flaw was found in the Linux kernel's batman-adv component. An out-of-bounds read vulnerability exists in the mcast module due to an incorrect size check when accessing the numdests header. This flaw could allow an attacker to read sensitive information from memory or cause a denial of service...

CVE-2026-72226

A flaw was found in the Linux kernel's batman-adv Better Approach To Mobile Ad-hoc Networking - Advanced module. An integer overflow can occur when calculating the length of a Translation Table Type-Length-Value TVLV unicast message. This overflow can lead to invalid safety checks, allowing an...

CVE-2026-72230

A flaw was found in the batman-adv Better Approach To Mobile Ad-hoc Networking - Advanced fragmentation module of the Linux kernel. The batadvfragsendpacket function, responsible for sending fragmented packets, does not properly free allocated memory when a packet is deemed unfragmentable due to ...

CVE-2026-72231

A flaw was found in the batman-adv Better Approach To Mobile Ad-hoc Networking module of the Linux kernel. An incorrect check during the handling of TT Topology Table requests can prevent the proper cleanup of request nodes when send buffer allocation fails. This can lead to a remote attacker...

CVE-2026-74310

In the Linux kernel, the following vulnerability has been resolved: vhost/net: complete zerocopy ubufs only once vhost-net initializes one ubufinfo per outstanding zerocopy TX descriptor and hands it to the backend socket. The networking stack may then clone a zerocopy skb before all skb referenc...

CVE-2026-72231

In the Linux kernel, the following vulnerability has been resolved: batman-adv: tt: avoid request storms during pending request batadvsendttrequest allocates a ttreqnode when none exists for the destination originator node. This should prevent that a multiple TT requests are send at the same time...

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-2026-72232

In the Linux kernel, the following vulnerability has been resolved: batman-adv: ensure minimal ethernet header on TX As documented in commit 8bd67ebb50c0 "net: bridge: xmit: make sure we have at least eth header len bytes", it is possible by for a local user with eBPF TC hook access to attach a t...

CVE-2026-72235

In the Linux kernel, the following vulnerability has been resolved: batman-adv: retrieve ethhdr after potential skb realloc on RX pskbmaypull in batadvinterfacerx could reallocate the buffer behind the skb. Variables which were pointing to the old buffer need to be reassigned to avoid an...

CVE-2026-72234

In the Linux kernel, the following vulnerability has been resolved: batman-adv: access unicastttvn skb-data only after skb realloc The pskbmaypull called by batadvgetvid could reallocate the buffer behind the skb. Variables which were pointing to the old buffer need to be reassigned to avoid an...

CVE-2026-72227

In the Linux kernel, the following vulnerability has been resolved: batman-adv: mcast: avoid OOB read of numdests header Before the access to struct batadvtvlvmcasttracker's numdests, it is attempted to check whether enough space is actually in the network header. But instead of using offsetofend...

CVE-2026-72228

In the Linux kernel, the following vulnerability has been resolved: batman-adv: frag: fix primaryif leak on failed linearization If the skb has a fraglist, it must be linearized before it can be split using skbsplit. But when this step failed, it must not only free the skb but also take care of t...

CVE-2026-72226

In the Linux kernel, the following vulnerability has been resolved: batman-adv: tt: prevent TVLV OOB check overflow A TT unicast TVLV contains the number of VLANs stored in it. This number is an u16 and gets multiplied by the size of the struct batadvtvlvttvlandata 8 bytes. The size can therefore...

CVE-2026-72230

In the Linux kernel, the following vulnerability has been resolved: batman-adv: frag: free unfragmentable packet The caller of batadvfragsendpacket assume that the skb provided to the function are always consumed. But the pre-check for an empty payload or the zero fragment size returned an error...
