CVE-2026-52914 — Linux: That accounting currently allows the accumulated fragment length to be truncated during updates.
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 fragment length to be truncated during updates. As a result, malformed fragment chains can bypass the intended validation and drive reassembly with inconsistent length state, leading CVSSv3.1 9.8 (CRITICAL) · EPSS 8th percentile
