EUVD-2026-39266

In the Linux kernel, the following vulnerability has been resolved: inet: frags: fix use-after-free caused by the fqdirpreexit flush On netns teardown, fqdirpreexit walks the fqdir rhashtable and flushes every fragment queue that is not yet complete using inetfragqueueflush. That helper frees all...

CVE-2026-52914

A flaw was found in the Linux kernel's batman-adv component. This vulnerability allows a local attacker to cause a denial of service DoS by sending malformed fragment chains. The flaw is due to incorrect accounting of fragment reassembly length, which can be truncated during updates, bypassing...

CVE-2026-52914

In the Linux kernel, the following vulnerability has been resolved: batman-adv: fix fragment reassembly length accounting batman-adv keeps a running payload length for queued fragments and uses it to validate a fragment chain before reassembly. That accounting currently allows the accumulated...

CVE-2026-48131 VPND IKE Fragment Reassembly - Heap Out-of-Bounds Write via Sequence Number Zero

The VPN service may mishandle an unexpected IKE fragment value received on the IKE port 500/UDP during the early stage of a connection attempt. This can cause the service to terminate unexpectedly, resulting in denial of service temporary disruption of VPN-related functionality...

CVE-2026-48131

CVE-2026-48131 concerns a VPN service handling of an unexpected IKE fragment value received on UDP/500 during early connection. The connected CVE data from CVELIST explicitly identifies the root cause as a Heap Out-of-Bounds Write via Sequence Number Zero during IKE fragment reassembly. This issu...
