Linux Kernel Vulnerability Affecting Data Integrity

CVE-2026-80586

What is CVE-2026-80586?

A vulnerability in the Linux kernel was identified that allows a remote peer to send malformed Dynamic Synchronization Signals (DSS) with incorrect sizes. This situation may lead to fields being inadvertently modified, resulting in data inconsistencies or potential access to uninitialized data. The vulnerability has been addressed by ensuring that affected fields are explicitly reset when unexpected sizes are detected in the DSS, enhancing the overall security posture of the system.
